Arina Puzriakova gene: BRF2 was added gene: BRF2 was added to COVID-19 research. Sources: Literature Mode of inheritance for gene: BRF2 was set to Unknown Added comment: Preprint: https://doi.org/10.1101/2020.07.01.20144592 Using UK Biobank data of 5,871 participants tested for COVID-19, including 193 deaths from 1,412 confirmed infections, authors identified 5 novel risk variants in 4 genes (ERAP2, BRF2, TMEM181, ALOXE3) associated with death from SARS-CoV-2 infection. Structural analysis showed the BRF2 SNP (rs138763430, D9N) at the Zn Ribbon domain alters the electrostatic potential surface, which in turn impacts the fundamental property of the domain to recognise nucleotide binding partners. Thus authors speculate that this variant most likely negatively alters the selectivity of the protein. However, whether this genetic variant has any physiological role on SARS-CoV-2 infection is yet to be determined. Sources: Literature |

| COVID-19 research v1.52 | IFNG |
Sarah Leigh changed review comment from: IFNG was identified through an OMIM search for potential viral susceptibility genes. Initial triage by Illumina (Alison Coffey and team) was given a Tier 3 grouping (experimental evidence and association data consistent with viral susceptibility). "Illumina review: From OMIM: Interferon-gamma (IFNG), or type II interferon, is a cytokine critical for innate and adaptive immunity against viral and intracellular bacterial infections and for tumor control. The importance of IFNG in the immune system stems in part from its ability to inhibit viral replication directly, but most importantly derives from its immunostimulatory and immunomodulatory effects. IFNG is produced predominantly by natural killer (NK) and natural killer T (NKT) cells as part of the innate immune response, and by CD4 (186940) and CD8 (see 186910) cytotoxic T lymphocyte (CTL) effector T cells once antigen-specific immunity develops (PMID: 178981204; Schoenborn and Wilson, 2007). From OMIM: PMID: 17215375: Huang et al. (2007) The IFNG gene SNP, -764 C>G (rs2069707) in the proximal promoter region next to the binding motif for HSF1 , was significantly associated with sustained virologic response to IFNA therapy in a cohort of hepatitis C virus-positive patients compared to a cohorts who had spontaneously cleared HCV infection or who had chronic HCV infection. Luciferase reporter and EMSA analyses showed that the -764G allele had 2- to 3-fold higher promoter activity and stronger binding affinity for HSF1 than the -764C allele. Huang et al. (2007) concluded that the -764C-G SNP is functionally important in determining viral clearance and treatment response in HCV-infected patients. From OMIM PMID: 12854077: An et al. (2003) reported an association between a SNP in the IFNG promoter region, -173 G>T, and progression to AIDS. In individuals with the rare -179T allele, but not in those with the -179G allele, IFNG is inducible by TNF. An et al. (2003) studied 298 African American HIV-1 seroconverters and found that the -179T allele was associated with accelerated progression to a CD4 cell count below 200 and to AIDS.

(2007) identified polymorphisms that explain nearly 15% of the variation among individuals in viral load during the asymptomatic set-point period of infection. One of these lies within an endogenous retroviral element and is associated with major histocompatibility allele HLA-B*5701 (142830.0003), whereas a second is located near the HLA-C gene. PMID:19933563 - Thomas et al. (2009) - Genotyped a previously identified varinat 35 kb upstream of the HLA-C gene in 1,698 patients of European ancestry with HIV. Tested cell surface expression of HLA-C in normal donors using an HLA-C-specific antibody. Found that the -35C allele is a proxy for high HLA-C cell surface expression, and that individuals with high surface expression better control viremia and progress more slowly to AIDS. Thomas et al. (2009) concluded that high HLA-C expression results in more effective control of HIV-1, possibly through better antigen presentation to cytotoxic T lymphocytes. PMID 21051598: International HIV Controllers Study performed a GWAS in a multiethnic cohort of HIV-1 controllers and progressors, and analyzed the effects of individual amino acids within the classical human leukocyte antigen (HLA) proteins and demonstrated HLA-C expression affects response to HIV - higher HLA-C expression is associated with better control of HIV-1. |

The FUT2 gene is expressed predominately in epithelial (mucosal) tissues. Individuals with inactivated FUT2 enzyme, known as “non secretors” do not express blood group antigens in these tissues and are resistant to several norovirus genotypes.

"Illumina review: Cell surface glycoprotein receptor involved in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation. DPP4 acts as a receptor for MERS-CoV - PMID: 24554656 - Barlan et al. (2014). MERS virus cell entry begins with the receptor-binding domains (RBDs) of the MERS-CoV protein virus spike (S) protein binding to blades 4 and 5 of the 8-blade propeller domain of DPP4. PMID:23486063 - Raj et al. (2013) - identified DPP4 as a functional receptor for hCoV-EMS (MERS CoV). Evidence from mouse models of involvment in susceptibility to MERS-CoV infection. PMID:24599590 - Zhao et al. (2014) - noted that rodents are not susceptible to MERS-CoV. They used an adenovirus vector expressing human DPP4 to generate mice sensitized to infection with MERS-CoV. These mice developed pneumonia characterized by extensive inflammatory cell infiltration with virus clearance after 6 to 8 days in a type I IFN- and T cell-dependent manner. Treatment with poly(I:C) was also efficacious in this model. PMID: 25589660 - Agrawal et al. (2015) developed a transgenic mouse model expressing human DPP4 that was susceptible to MERS-CoV infection, with high titers of virus detectable in brain and lung and later in other organs. PMID: 26124093 - Pascal et al. (2015) - obtained a mouse model susceptible to intranasal infection with MERS-CoV. Human monoclonal antibodies binding to the MERS-CoV S protein neutralized all variants of the virus and prevented entry into target cells. The antibodies could both prevent and treat mice humanized for DPP4. Pascal et al. (2015) concluded that the model will be valuable for assessing treatments for MERS-CoV infection and disease. PMID:31883094 - Leist et al. (2020) - generated a mouse model susceptible to MERS-CoV infection - used C57BL/6J mice and CRISPR/Cas9 to substitute human residues at positions 288 and 330 (A288L and T330R). Strollo et al. (2020) and Bassedine et al. (2020) suggested that DPP4 could affect severity of infection and also be a therapeutic target: PMID:32336077 - Strollo et al. (2020) - propose a role for DDP4 as a functional receptor for SARS-CoV-2 and ask the question if DPP4 is directly involved in SARS-CoV-2 cell adhesion/virulence, and whether DPP4 inhibition might be a therapeutic strategy for preventing infection. PMID:32394639 - Bassedine et al. (2020) - modeling of the structure of SARS-CoV-2 spike glycoprotein predicts that it can interact with human DPP4 in addition to ACE2. Notes that increased DPP4 expression and activity are associated with diabetes, obesity, and metabolic syndrome, all of which have been reported to influence COVID‐19 severity. DPP4 inhibitors (gliptins), which vary in their interactions with the active site of the enzyme, may have immunomodulatory and cardioprotective effects that could be beneficial in COVID‐19 cases. PMID:31964246 - Keline-Weber at al. (2020) - Identified 14 polymorphisms in DPP4 from public databases that alter amino acid residus required for MERS-CoV S binding. Introduction of the respective variants into DPP4 revealed that all except one (Δ346-348) were compatible with robust DPP4 expression. Four polymorphisms (K267E, K267N, A291P and Δ346-348) strongly reduced binding of MERS-CoV S to DPP4 and S protein-driven host cell entry, as determined using soluble S protein and S protein bearing rhabdoviral vectors, respectively. Two polymorphisms (K267E and A291P) were analyzed in the context of authentic MERS-CoV and were found to attenuate viral replication. Collectively, we identified naturally-occurring polymorphisms in DPP4 that negatively impact cellular entry of MERS-CoV and might thus modulate MERS development in infected patients. |

Initial triage by Illumina (Alison Coffey and team) was given a Tier 2 grouping (experimental and/or genetic evidence, suggesting a biological role linking to corona viruses, may not be a GDA). Illumina review: CLEC4M is a C-type lectin gene serving as cell adhesion receptor and pathogen recognition receptor. It functions as a cellular receptor for variety of viruses, including HIV-1, hepatitis C, Ebola, and SARS-coronavirus. A highly polymorphic variable number tandem repeat (VNTR) at the neck-region of CLEC4M had been associated with genetic predisposition to some infectious diseases, however, genetic association studies have shown conflicting results about these associations (PMID:16991095;16369534;12738250;16364081;17321900;18697825;17534354;17534355). From OMIM: Associated with protection against SARs infection. PMID: 15496474: Jeffers et al. (2004) identified the cellular gylcoprotein CD209L (CLEC4M) as as an alternative receptor for SARS-CoV. CD209L is expressed in human lung in type II alveolar cells and endothelial cells, both potential targets for SARS-CoV. Several other enveloped viruses, including Ebola and Sindbis, also use CD209L as a portal of entry, and HIV and hepatitis C virus can bind to CD209L on cell membranes but do not use it to mediate virus entry. Jeffers et al. (2004) suggested that the large S glycoprotein of SARS-CoV may use both ACE2 and CD209L in virus infection and pathogenesis. PMID 16369534: Chan et al. (2006) - demonstrated that individuals homozygous for CLEC4M tandem repeats are less susceptible to SARS infection. CLEC4M was expressed in both non-SARS and SARS-CoV-infected lung. Compared with cells heterozygous for CLEC4M, cells homozygous for CLEC4M showed higher binding capacity for SARS-CoV, higher proteasome-dependent viral degradation, and a lower capacity for trans infection. Thus, homozygosity for CLEC4M plays a protective role during SARS infection. PMID: 17534354: Tang et al. (2007) - performed genotyping studies in SARS patients and controls and found no support for an association between homozygosity for CLEC4M and protection against SARS. PMID:17534355: Zhi et al. (2007) also failed to replicate the study by Chan et al. (2006). Chan et al. (2007) disputed the validity of both studies. PMID 18697825:Li et al. (2008) - genotyped SNPs in CLEC4M and other genes in the C-type lectin cluster in 181 Chinese SARS patients and 172 controls from an ethnically matched population and found no significant association with disease predisposition or prognosis. However, they detected a population stratification of the CLEC4M variable number tandem repeat (VNTR) alleles in a sample of 1,145 Han Chinese from different parts of China (northeast, south, and southwest). Analysis extended to 742 individuals from 7 ethnic minorities showed that those located along the Silk Road in northwestern China, where there is significant admixture with the European gene pool, had a low level of homozygosity, similar to European populations. Li et al. (2008) concluded that there is no SARS predisposition allele in the lectin gene cluster at chromosome 19p13.3, and that the previously reported association with polymorphisms in the CLEC4M neck region may be due to population stratification. |

Illumina review: One SNP associated with susceptibility to HIV infection, severity of dengue disease, increased risk of TB and severity of SARS infection. Pathogen-recognition receptor expressed on the surface of immature dendritic cells (DCs) and involved in initiation of primary immune response. Thought to mediate the endocytosis of pathogens which are subsequently degraded in lysosomal compartments. The receptor returns to the cell membrane surface and the pathogen-derived antigens are presented to resting T-cells via MHC class II proteins to initiate the adaptive immune response. From OMIM:The C-type lectin receptors are involved in the primary interface between host and pathogens. PMID:15564514: Martin et al. (2004) - European Americans at risk for parenteral HIV infection were more likely to carry the -336C SNP in the promoter of DCSIGN. This association was not observed in those at risk for mucosally acquired infection. Although the -336C SNP was common in African Americans, no significant association with risk of infection was observed in this group. PMID:15838506: Sakuntabhai et al. (2005) found that the same CD209 promoter polymorphism reported by Martin et al. (2004) (-336A>G in this study), was associated with severity of dengue disease. Specifically, the G allele of the variant was associated with strong protection against dengue fever as opposed to dengue hemorrhagic fever. PMID:16379498:Barreiro et al. (2006) looked at CD209 polymorphisms in 351 TB patients and 360 healthy controls from a South African Coloured population living in communities with some of the highest reported incidence rates of TB in the world. Identified two variants in the CD209 promoter, -871A and -336G, that were associated with increased risk of TB. PMID:20864747: Chan et al. (2010) - A single nucleotide polymorphism in the promoter region of the DC-SIGN gene is associated with disease severity in SARS. In the DC_SIGN promoter region, a single SNP, -336A>G has been found to affect transcription of DC-SIGN in vitro and is associated with susceptibility for HIV-1 and M. tuberculosis infectsions and with the severity of dengue (PMID:15838506;15838506;16379498). Large case-control study - genotyped the SNP in 824 SARS patients and 471 controls. Showed no association with susceptibility to infection but SARS patients carrying the DC-SIGN promoter -336G variant had lower risk of having higher lactate dehydrogenase levels on admission, an independent prognostic indicator for severity of SARS-CoV infection. In vitro functional studies demonstrated that the DC-SIGN -336G promoter provided a less effective binding site and lower promoter activity, which may lead to reduced DC-SIGN protein expression and hence may contribute to a reduced immune-response with reduced lung injury during the progression of SARS infection. |

| COVID-19 research v1.1 | DAG1 |
Rebecca Foulger changed review comment from: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): The DAG1 gene encodes 2 dystroglycan proteins, both of which are dystrophin-associated glycoproteins (DAGs) (OMIM:128239). Alpha-Dystroglycan (a-DG) is a common receptor for lymphocytic choriomeningitis virus (LCMV) and several other arenaviruses including the human pathogenic Lassa fever virus (Imperiali et al. 2005; Kunz et al. 2009; Rojek et al. 2007). PubMed 16254364: Imperiali et al. (2005) - alpha-Dystroglycan (a-DG) was identified as a common receptor for lymphocytic choriomeningitis virus (LCMV) and several other arenaviruses including the human pathogenic Lassa fever virus. Arenaviruses are enveloped, single-stranded RNA viruses with a bisegmented ambisense genome. Susceptibility toward LCMV infection differed in various cell lines despite them expressing comparable levels of DG, suggesting that posttranslational modifications of a-DG would be involved in viral receptor function. Demonstrated that glycosylation of a-DG, and in particular, O mannosylation, which is a rare type of O-linked glycosylation in mammals, is essential for LCMV receptor function. Cells that are defective in components of the O-mannosylation pathway showed strikingly reduced LCMV infectibility. As defective O mannosylation is associated with severe clinical symptoms in mammals such as congenital muscular dystrophies, it is likely that LCMV and potentially other arenaviruses may have selected this conserved and crucial posttranslational modification as the primary target structure for cell entry and infection. PMID 19324387: Kunz et al. (2009) - Old World arenaviruses LCMV (lymphocytic choriomeningitis virus) and LASV (Lassa virus) enter the host cell predominantly via a novel and unusual endocytotic pathway independent of clathrin, caveolin, dynamin, and actin. Infection of cells with LCMV and LASV depends on DG, this unusual endocytotic pathway could be related to normal cellular trafficking of the DG complex. Arenavirus particles may target DG for an endocytotic pathway not normally used in uninfected cells thereby inducing an entry route specifically tailored to the pathogen's needs. PMID 17360738: Rojek et al. (2007) - Found that protein O mannosylation of α-DG is crucial for the binding of arenaviruses of distinct phylogenetic origins, including LFV, Mobala virus, and clade C New World arenaviruses.

Alpha-Dystroglycan (a-DG) is a common receptor for lymphocytic choriomeningitis virus (LCMV) and several other arenaviruses including the human pathogenic Lassa fever virus (Imperiali et al. 2005; Kunz et al. 2009; Rojek et al. 2007). PubMed 16254364: Imperiali et al. (2005) - alpha-Dystroglycan (a-DG) was identified as a common receptor for lymphocytic choriomeningitis virus (LCMV) and several other arenaviruses including the human pathogenic Lassa fever virus. Arenaviruses are enveloped, single-stranded RNA viruses with a bisegmented ambisense genome. Susceptibility toward LCMV infection differed in various cell lines despite them expressing comparable levels of DG, suggesting that posttranslational modifications of a-DG would be involved in viral receptor function. Demonstrated that glycosylation of a-DG, and in particular, O mannosylation, which is a rare type of O-linked glycosylation in mammals, is essential for LCMV receptor function. Cells that are defective in components of the O-mannosylation pathway showed strikingly reduced LCMV infectibility. As defective O mannosylation is associated with severe clinical symptoms in mammals such as congenital muscular dystrophies, it is likely that LCMV and potentially other arenaviruses may have selected this conserved and crucial posttranslational modification as the primary target structure for cell entry and infection. PMID 19324387: Kunz et al. (2009) - Old World arenaviruses LCMV (lymphocytic choriomeningitis virus) and LASV (Lassa virus) enter the host cell predominantly via a novel and unusual endocytotic pathway independent of clathrin, caveolin, dynamin, and actin. Infection of cells with LCMV and LASV depends on DG, this unusual endocytotic pathway could be related to normal cellular trafficking of the DG complex. Arenavirus particles may target DG for an endocytotic pathway not normally used in uninfected cells thereby inducing an entry route specifically tailored to the pathogen's needs.

Sarah Leigh Added comment: Comment on list classification: Not associated with a phenotype in OMIM or in Gen2Phen. However, CD200 is a membrane protein that interacts with CD200R on the surface of immune cells and delivers an inhibitory signal to suppress immune functions as a "check point" to prevent an excessive inflammatory response . Viral homologs of CD200, such as rat cytomegalovirus e127 protein, may play a role in suppressing the host immune response (PMID 19587022). Conversely, in coronavirus infection, inhibition of CD200-CD200R1 results in restoring IFN production and increasing virus clearance (PMID 30032349). Therefore understanding of the mechanisms of CD200-CD200R action may help in development of treatments. |

| COVID-19 research v0.349 | HDAC6 |
Rebecca Foulger commented on gene: HDAC6: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): Histone deacetylase 6 (HDAC6) is a unique cytoplasmic deacetylase that regulates various important biological processes by preventing protein aggregation and deacetylating different non-histone substrates. Growing evidence has indicated a dual role for HDAC6 in viral infection and pathogenesis: HDAC6 may represent a host defence mechanism against viral infection by modulating microtubule acetylation, triggering antiviral immune response and stimulating protective autophagy, or it may be hijacked by the virus to enhance proinflammatory response (Zheng et al, 2017). HDAC6 promotes the aggresome/autophagic degradation of the viral polyprotein Pr55Gag to inhibit HIV-1 production and infection (Hernández et al, 2019). Depletion of HDAC6 expression (in vitro) led to impaired antiviral responses against RNA viruses, but not against DNA viruses. HDAC6 knockout mice were highly susceptible to RNA virus infections compared to wildtype mice (Choi et al, 2016). Overexpression of Hdac6 enhances resistance to virus infection in embryonic stem cells and in mice (Wang et al, 2015). Literature: PMID: 27959772 - Zheng et al. (2017) (Review) This review highlights current data illustrating the complexity and importance of HDAC6 in viral pathogenesis. HDAC6 has both proviral and antiviral effects. HDAC6 can inhibit infection of both RNA and DNA virus by modulating microtubule (MT) cytoskeleton and stimulating selective autophagy and restrict viral diffusion by triggering antiviral immune response. However, RNA viruses can also utilize HDAC6-mediated aggresome pathway or proinflammatory response to facilitate viral pathogenesis (Fig 1 and Table 1) • HDAC6 triggers antiviral gene expression upon RNA virus infection (Fig 3a) • HDAC6 interacts with Vif or A3G and competes for Vif–A3G interaction through its BUZ domain, impairs the incorporation of Vif into nascent virions and finally controls HIV-1 infectiveness (Fig 4) • HDAC6 facilitates viral uncoating and pathogenesis (Fig 5) Findings support exploration of a potential therapeutic role for restricting viral pathogenesis by targeting HDAC6. PMID: 31736889: Hernández et al. (2019) - HIV Nef is a central auxiliary protein in HIV infection and pathogenesis. Results from the study indicate that HDAC6 promotes the aggresome/autophagic degradation of the viral polyprotein Pr55Gag to inhibit HIV-1 production • HIV-1 Nef viral protein induces HDAC6 Degradation (Enzyme degradation by recombinant HIV-1 Nef in HEK-293T cells in both endogenous and over expressed HDAC6 is shown in Fig 1) • Mutated Nef protein Nef-PPAA did not promote HDAC6 degradation (Figure 3A, quantified in Figure 3B). This fact may indicate that this motif is involved in Nef-mediated HDAC6 interaction and/or processing, or that a conformational change in the mutated viral protein abrogates the degradative activity observed with the wt-Nef (Figures 1–3) • Nef assures viral production and infection by targeting HDAC6, stabilizing Pr55Gag and Vif, thereby facilitating Pr55Gag location and aggregation at plasma membrane, and subsequent virus production and infection capacity (events summarized by schematic illustrations in Figure 10) PMID: 26746851: Choi et al.

In vitro • HDAC6 deficiency reduces the innate immune response on mouse macrophage and mouse embryonic fibroblast (Fig 3) • HDAC6 and RIG-I transiently interact in response to RNA viral infection (Fig 5A and B) and HDAC6 regulates the binding of RIG-I to 50 pppdsRNA by deacetylating RIG-I (Fig 5G) PMID: 25482409 Wang et al. (2015) - This is another study that provides a proof of principle of antivirus function by Hdac6 in vivo.

| COVID-19 research v0.349 | PVR |
Rebecca Foulger commented on gene: PVR: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): PVR, or CD155, belongs to a large family of immunoglobulin (Ig)-like molecules called nectins and nectin-like proteins, which mediate cell-cell adhesion, cell migration, and cell polarization through interaction with other nectins. It is both a viral receptor and immunomodulatory protein and is involved in many biological processes. PVR serves as the entry receptor for poliovirus and thereby is responsible for human susceptibility to poliovirus infection. Susceptibility to poliovirus is a function of the presence or absence of the cellular receptor to which the virus binds as the first step in poliovirus replication. Mendelsohn et al. (1986) succeeded in transforming a human poliovirus receptor gene into mouse L cells, which are ordinarily resistant to poliovirus infection because they do not bear a poliovirus receptor. Monoclonal antibody directed against the HeLa cell poliovirus receptor site was used in rosette assays to identify poliovirus-sensitive transformants. Evidence for PVR as a Viral Receptor, regulator of immune function and its role in cancer is described in Bowers et al (2017). CD155-deficient mice develop normally without displaying an overt phenotype. However, the animals are distinguished by distinct deficits in the development of a regular humoral immune response (Maier et al, 2007) Literature: PMID: 28870470 - Bowers et al, 2017 (Review) - PVR is an important cell adhesion protein and is involved in the transendothelial migration of leukocytes. PVR undergoes alternative splicing, generating 4 unique splice forms. Protein isoforms and interactions with Poliovirus are summarized in Table 1. In addition to its role as a receptor for the human poliovirus, several native biological functions have also been uncovered. PVR is an important cell adhesion protein and is involved in the transendothelial migration of leukocytes. Through its interactions with CD226 and TIGIT, transmembrane proteins found on leukocytes, PVR is a key regulator of the cell-mediated immune response. In this review more evidence is available for PVR as a Viral Receptor and PVR as a regulator of immune function PMID: 25113908 - Bolduan et al, 2014 - NL4-3 Vpu protein from HIV downregulates the activating NK cell receptor CD155 from the cell surface by the conserved alanine residues Ala-10, Ala-14 and Ala-18 of its TM domain to evade NK cell mediated immune response against HIV-1 infected cells (Hela cells) PMID: 19815499 - Stanietsky et al, 2009 - TIGIT (a protein expressed by all human NK cells) binds PVR and PVRL2 but not PVRL3 and inhibits NK cytotoxicity directly through its ITIM. PMID: 12943679 - Baury et al, 2003 -As the extracellular domains of the sPVR (soluble PVR) isoforms are identical to the extracellular domain of transmembrane PVR, they can compete with transmembrane PVR for the canyon-like receptor binding site of poliovirus. When sPVR is overexpressed in poliovirus susceptible HeLa cells, it significantly reduces viral entry and viral infectivity PMID: 17621371 - Maier et al, 2007 - In this study, Maier et al explore the expression profile of CD155 on murine hematopoietic cells utilizing newly generated mAb. They report on the establishment and immunological analysis of mice deficient in CD155. CD155-deficient mice (knock out) develop normally without displaying an overt phenotype. However, the animals are distinguished by distinct deficits in the development of a regular humoral immune response. Whereas systemic challenges revealed no differences, orally administered antigen evoked less efficient IgG and IgA antibody responses (Figure 7) despite of normal IgM titers when compared to wild-type mice. Therefore, CD155 may assist in an efficient humoral immune response generated within the intestinal immune system. PMID: 28800489 - Lin et al, 2017 - Amino acid changes in the C’C”D region in poliovirus receptor domain 1 disrupt poliovirus binding. We substituted this region of Pvr into the corresponding region of a murine homolog, nectin-2.

PMID: 2597248 - Kanemaru et al, 2015 - Mice genetically deficient in CD155 or treated with anti-CD155 Ab exhibited attenuated Th1-type contact hypersensitivity.

Nectin-1 knockout mice inoculated with HSV in the hippocampus demonstrated that nectin-1 is necessary for neurologic disease caused by HSV (PMID:19805039). PMID 11756979 - Struyf et al. (2002) - Searched for polymorphisms in HVEM, nectin-1, and nectin-2 via sequencing in individuals shown to immune seronegative for herpes simplex virus (HSV). These individuals showed T cell responses to HSV antigens and did not have anti-HSV antibodies detected in their serum. There were three individuals that were immune seronegative, three with no signs of cellular or humoral immunity, and three with frequent reactivations of HSV who had antibody and T cell responses to HSV. One individual in the study (true seronegative as demonstrated by negative testing for HSV-1 and HSV-2 and no HSV-specific T cell immunity) was identified to have a variant in nectin-1 (c.752G>A, p.Arg199Gln) in addition to one missense variant in HVEM (table 2). This variant was screened for 644 healthy White individuals and 17 were shown to be heterozygous for the p.Arg199Gln variant and one individual had a different missense variant at the same residue. The p.Arg199Gln variant occurs in the first constant-like domain for the protein. A different domain, the N-terminal variable-like domain, has previously been shown as important for virus entry into the cell. PMID 12072525 - Martinez and Spear (2002) - Investigated whether residues 75-77 and 85 of nectin-1 (homologous to regions A and B of nectin-2) are necessary for HSV-1 entry into CHO-K1 cells (which are resistant to the entry of alphaherpesviruses unless they are created to express a gD receptor). When there were mutants involving both residues 77 and 85, there was severely diminished ability of HSV-1 or HSV-2 to enter the cell and was unable to find to soluble forms of HSV-1 and HSV-2 (table 1; fig. 3). Note that these mutants allowed entry of PRV and BHV-1. PMID 19805039 - Kopp et al. (2009) - Nectin-1 knockout (KO) mice were inoculated intracranially and into the hippocampus with herpes simplex virus (HSV) and infection of neurons compared to HVEM KO mice, HVEM/nectin-1 KO mice, and controls. Nectin-1 KO mice were resistant to disease, as were the double KO mice at doses of the virus up to 100x needed to cause disease as compared to the wildtype and HVEM KO mice (Fig. 1). Nectin-1 is necessary for neurologic disease caused by HSV. Viral antigen was not detected in brain sections from double KO mice, but could be detected for nectin-1 KO mice (limited regions), HVEM-KO mice and wildtype (more widespread) (Fig. 2A). HSV was shown to be located to the ventricular surfaces in nectin-1 KO mice and confirmed as non-parenchymal cells (Fig. 2B). |

Rebecca Foulger commented on gene: MIR155: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): MIR155 (also referred to as BIC) is an endogenous noncoding RNA involved in regulation of the immune response, in particular T-cell differentiation, and in regulation of innate immunity (PMID: 32233818; 217121651;1746328969;20852130). This miRNA has been associated with various virus infections (PMID: 32233818;28139244;23686237;26072128). miR-155-5p expression has been shown to be induced in mice infected with influenza A virus (PMID: 32308197 - in this study, lung injury by ARDS was attenuated by deletion of miR-155, making this miRNA a potential therapeutic target in the context of COVID-19). Through single cell and bulk RNA profiling of SARS-CoV-2 and SARS-CoV infections in three human cell lines (H1299, Caco-2 and Calu-3 cells), Emanuel et al. (2020) (bioRxiv preprint doi: https://doi.org/10.1101/2020.05.05.079194) demonstrated strong expression of the immunity and inflammation-associated microRNA miRNA-155 upon viral infection with both viruses. Both viruses triggered a 16-fold upregulation of one form of miR-155 and a 3-fold upregulation of another. A role for MIR155 in viral susceptibility for a range of viruses and the immune response has also been demonstrated in a series of mouse models: PMID 23601686: In Mir155 -/- mice, Dudda et al. (2013) observed severely reduced accumulation of Cd8-positive T cells during acute and chronic viral infections with impaired control of viral replication. Lack of Mir155 led to an accumulation of Socs1 resulting in defective cytokine signaling through Stat5. Dudda et al. also concluded that MIR155 and its target, SOCS1, are key regulators of CD8-positive T cells. PMID 23275599: Lind et al. (2013) found that mice lacking Mir155 had impaired Cd8 positive T-cell responses to infections with lymphocytic choriomeningitis virus and the intracellular bacteria Listeria monocytogenes and concluded that MIR155 is required for acute CD8-positive T-cell responses and proposed that targeting MIR155 may be useful in modulating immune responses. PMID 24516198: Bhela et al. (2014) – 75 to 80% of MIR155 null mice infected ocularly with herpes simplex virus (HSV)-1 developed herpes simplex encephalitis with elevated viral titers in brain, but not in cornea. Immunohistochemical and flow cytometric analyses in Mir155-null mice showed diminished Cd8-positive T-cell numbers, functionality, and homing capacity. Adoptive transfer of HSV-1-immune Cd8-positive T cells to Mir155-null mice 24 hours after infection provided protection from HSE. The authors concluded that MIR155 deficiency results in enhanced susceptibility of the nervous system to HSV-1 infection. |

| COVID-19 research v0.348 | KLF2 |
Rebecca Foulger commented on gene: KLF2: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): KLF2 is a member of the Kruppel-like factor (KLF) family of zinc finger transcription factors that function in cell differentiation, quiescence, and homeostasis. It also plays a regulatory role in inflammation-related pathways (Jha and Das 2017). Richardson et al. (2012) showed that KLF2 acts as a host factor that modulates CCR5 expression in CD4 T cells and influences susceptibility to infection with CCR5-dependent HIV-1 strains. Huang et al. (2017) showed through both network analyses and experimental results that KLF2 plays a central role in regulating many genes associated with acute respiratory distress syndrome (ARDS) identified by GWAS and that overexpression of KLF2 in vivo in mice could mitigate lung injury and expression of inflammatory genes, including that induced by influenza A virus. PMID 17141159: Lee et al. (2006) - KLF2 deficient mice die in prenatal stage due to vascular defects, highlighting its crucial role in embryonic development. Lethal high-output heart failure, as found in the KO mice, was also observed in zebrafish embryos after morpholino inhibition of the Klf2 ortholog klf2a. CD4+ T cells from KLF2-deficient mice expressed multiple inflammatory chemokine receptors, suggesting that loss of KLF2 leads to redirection of naïve T cells to nonlymphoid sites (Sebzda et al., 2008). PMID 19592277: Weinreich et al. (2009) - Demonstrated upregulation of the chemokine receptor CXCR3 on KLF2-deficient T cells (Fig. 1). KLF2-deficient T cells also overproduced IL-4 (Fig. 5). PMID 22988032: Richardson et al. (2012) - Tested whether the abundance of KLF2 after T cell activation regulates CCR5 expression and, thus, susceptibility of a T cell to CCR5-dependent HIV-1 strains (R5). Introduced small interfering RNA targeting KLF2 expression and demonstrated that reduced KLF2 expression also resulted in less CCR5 (Fig. 3). Introduction of KLF2 under control of a heterologous promoter could restore CCR5 expression and R5 susceptibility to CD3/28 costimulated T cells and some transformed cell lines (Fig. 5, 6). KLF2 is a host factor that modulates CCR5 expression in CD4 T cells and influences susceptibility to R5 infection. PMID 29125549: (review) Jha and Das (2017) - KLF2 also plays a critical regulatory role in various inflammatory diseases and their pathogenesis. PMID 27855271: Huang et al. (2017) - Animal and in vitro models of acute lung injury were used to characterize KLF2 expression and its downstream effects responding to influenza A virus (A/WSN/33 [H1N1]), tumor necrosis factor-α, LPS, mechanical stretch/ventilation, or microvascular flow to examine the role of the gene in endothelial barrier disruption and cytokine storm in experimental lung injury. Pulmonary Klf2 was down-regulated by inflammation induced by influenza A/WSN/H1N1 virus (H1N1) infection, LPS administration, or LPS administration followed by high tidal volume ventilation in vivo (Fig. 1). It was also down-regulated by pathologic stretch and inflammatory stimuli (Fig. 2). Knockdown of endogenous KLF2 reduces Rac1 activation in human pulmonary microvascular cells, whereas adenovirus-mediated transduction with KLF2 promoted Rac1 activation (Fig. 3). Computational predictive pathway analysis suggested that KLF2 acts to regulate ARDS-associated GWAS genes, including ACE, NAD(P)H, NQO1, SERPINE1/PAI-1, TNF, and NF-kappaB. Expression studies in mice confirmed this regulatory role (Fig. 8). Overexpression of KLF2 in vivo in mice could also mitigate lung injury and expression of inflammatory genes (Fig. 7). |

| COVID-19 research v0.348 | FOLR1 |
Rebecca Foulger commented on gene: FOLR1: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): The FOLR1 gene encodes the folate receptor alpha (FR alpha), a glycosyl-phosphatidylinositol-linked (GPI-linked) protein that binds folic acid for transport into the cytoplasm. Chan et al. (2001) used genetic complementation to identify FR-alpha as a cofactor for cellular entry of pseudo Marburg (MBG) virus and EBO-Z pseudotype into otherwise non permissive cells. Further experiments showed FR alpha specifically binds glycoproteins of these viruses to mediate syncytia (Chan et al. 2001). PMID 11461707; Chan et al. (2001) - A complementation screen identified FR alpha as a cofactor for cellular entry of pseudo Marburg (MBG) virus into otherwise non permissive Jurkat-EctR cells (fig 1). FACs analysis showed FR alpha was present on the cell surface of other cell lines permissive for MBG infectivity (Hela cells, Vero E6, human and dog osteosarcoma cells (fig 2). FR alpha specific antagonists inhibited MBG entry (Fig 4) phospholipase C (PLC) cleaves the FR alpha receptor, cells pretreated with PLC showed decreased infectivity. When 293T cells overexpressing MBF GP were co-cultured with cells overexpressing FR alpha syncytia formation was observed, indicating that this type of membrane fusion is also mediated by FRalpha (fig 5). A similar set of experiments showed that FR alpha is also a cofactor for cellular entry of EBO-Z pseudo viruses. Yang et al. (2019) preprint: https://doi.org/10.1101/618306 - Poliovirus (PV), a prototype for human pathogenic positive-sense RNA enteroviruses, transport multiple virions en bloc via infectious extracellular vesicles secreted from host cells. Yang et al. show that in these microvesicles less than 10% of proteins are viral. 168 host cell proteins were identified in the MVs including involved in both caveolar-mediated and mediated endocytic virus entry pathways genes (ITGB1, B2M, FYN, CD55 {DAF}, HLA-A, FLNA, ACTB, RAC1, TFRC {CD71}, FOLR1). |

| COVID-19 research v0.348 | CD28 |
Rebecca Foulger commented on gene: CD28: Evidence Summary from Illumina curation team: CD28 is a transmembrane receptor expressed on the surface of T cells and is required for the immune cell activation and proliferation of naïve and memory T cells. CD28 knockout mice have an increased susceptibility to ECTV, a host specific virus which causes mousepox. Upon infection, CD28 deficient mice showed a 40% mortality within 14 days while wild-type control mice did not show any symptoms of disease (Fang et al. 2008). In cell culture experiments, CD28 protein surface levels were found to be downregulated by HIV-1 accessory proteins Nef and Vpu (Pawlak et al. 2018). In severe cases of COVID-19 infection, immuno-dysregulation may lead to a decrease of CD28+ cytotoxic suppressor T cells (Tufan et al. 2020, review) PMID: 29329537; Pawlak et al.(2018) - CD28 is a transmembrane receptor expressed on the surface of T cells. It is essential for immune cell activation and proliferation of naïve and memory T cell. Cell culture experiments using CD4+ Sup-T1 cells or primary CD4+ T cells and infected with VSV-G pseudotyped NL4.3 viruses showed that the HIV-1 accessory proteins Nef and Vpu modify the immune response and increase viral persistence by decreasing the cell surface levels of CD28 (fig.1). PMID: 32299202; Tufan et al. (2020) Review. SARS-CoV-2 infection can lead to immune dysregulation through affecting the subset of T cells. In severe cases of COVID-19 infection, it was observed that the percentage of naïve helper T cells amplifies while the percentage of memory helper T cells and CD28+ cytotoxic suppressor T cells decreases. PMID: 17114476; Fang et al. (2008) - CD28 KO mice in a mousepox-resistant B6 background infected with ECTV showed a 40% mortality 7–14 days PI (Fig. 1A) and all remaining CD28KO mice developed mousepox (Fig. 1, B and C). All control wild-type B6 mice survived the infection without any symptoms of disease. CD28 KO mice that survived past 14 days PI gradually recovered from the disease and survived indefinitely. A comparison of CD8+ T cell responses to ECTV and VACV suggests that the main reason for the susceptibility of CD28 KO mice to mousepox is a reduced response at the early stages of infection. |

| COVID-19 research v0.347 | IDE | Alison Coffey commented on gene: IDE: Evidence Summary from Illumina curation team: Insulin-degrading enzyme (IDE), also known as insulysin, is a member of the zinc metalloproteinase family that was initially implicated in insulin degradation. It is highly conserved among different species and has the ability to interact with a variety of functionally unrelated ligands that share little homology in their primary amino acid sequences. Several human viruses use enzymes as receptors. Li et al. (2006) (PMID 17055432) established IDE as a cellular receptor for both cell-free and cell-associated Varicella-zoster virus (VZV), the cause of chickenpox and shingles in humans. VZV is likely spread as cell-free virus to susceptible hosts but transmitted by cell-to-cell spread in the body and in vitro. Li et al. (2006) showed that IDE interacts with the VZV glycoprotein E (gE) (which is essential for virus infection) through its extracellular domain. Downregulation of IDE by siRNA, or blocking of IDE with antibody, with soluble IDE protein extracted from liver, or with bacitracin inhibited VZV infection. Cell-to-cell spread of virus was also impaired by blocking IDE. Transfection of cell lines impaired for VZV infection with a plasmid expressing human IDE resulted in increased entry and enhanced infection with cell-free and cell-associated virus. Li et al. (2010) subsequently reported that a recombinant soluble IDE (rIDE) enhanced VZV infectivity at an early step of infection associated with an increase in virus internalization, and increased cell-to-cell spread. In 2017, Hahn et al. demonstrated that mature HIV-1 p6 protein (stability of which inversely affects the replication capacity of HIV-1) is a substrate for IDE. IDE is both sufficient and required for the degradation of p6, which is approximately 100-fold more efficiently degraded by IDE than its eponymous substrate insulin. An IDE specific inhibitor, 6bK, and exogenous insulin, were both shown to interfere with X4-tropic HIV-1 replication in activated PBMCs, most probably by competing with p6 for degradation by IDE. In addition, an IDE-insensitive p6 mutant of HIV-1 exhibits impaired replication capacity but is insensitive to treatment with insulin or 6bK. Conversely, neither virus release and maturation, nor the amounts of particle associated Vpr and p6 itself were altered in IDE knock out cells. The data support a model in which IDE is responsible for the rapid degradation of p6 entering the cell as part of the incoming virion, a process that appears to be crucial to achieve optimal X4-tropic virus replication. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| COVID-19 research v0.347 | DEFA1 | Alison Coffey commented on gene: DEFA1: Evidence Summary from Illumina curation team: DEFA1, or HNP1, is a member of the defensin family of host defense peptides, a group of microbicidal and cytotoxic peptides made by neutrophils. Defensins are known to have a role in innate immunity as a core host-protective component against bacterial, viral and fungal infections (Xu and Wuyaun, 2020). Defensins have direct antiviral activity in cell culture, with varied mechanisms for individual viruses. Defensins also have a potent immunomodulatory activity that can alter innate and adaptive immune responses to viral infection and are able to target multiple steps of host-virus interactions to reduce infectivity of both enveloped and non-enveloped viruses. Targets include viral envelopes, glycoproteins, and capsids or host cells. DEFA1 is well-recognized for its direct anti-HIV activity, it also restrains HIV-1 uptake by inhibiting Env-mediated viral fusion and downregulating host cell surface expression of CD4 and coreceptor CXCR4. Post-entry inhibition of enveloped viruses such as HIV-1 and influenza by DEFA1 is mediated through interfering with cell signaling pathways such as PKC that are required for viral replication (Xu and Wuyaun, 2020). An unpublished study by Kit and Kit (2020), demonstrated in silico that the affinity of human alpha-defensins 1, 2, 3 and 5 to SARS-CoV-2 spike protein is higher than that of the SARS-CoV-2 spike protein towards ACE2. The authors suggest that these alpha-defensins may serve as primary factors in protecting lung tissue from COVID-19 viral infection. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| COVID-19 research v0.347 | CXADR | Alison Coffey commented on gene: CXADR: Evidence Summary from Illumina curation team: The coxsackie and adenovirus receptor (CXADR or CAR), also known as CAR-like membrane protein (CLMP), was first identified as a high affinity receptor for adenovirus serotypes 2 and 5 and coxsackie viruses group B. CXADR is developmentally regulated and plays an important role in cardiac development. The protein is a transmembrane receptor and plays a key role in controlling adhesion between adjacent epithelial cells. It is also implicated in controlling both recruitment of immune cells and in tumorigenesis (Zapater et al. 2017). Vehik et al. (2018) concluded that a SNP within the CXADR region is associated with islet autoimmunity. In response to exogenous TNF?, CAR promotes transmigration of leukocytes both in vitro and in vivo. suggesting that CAR may be an important receptor in the control of inflammation. As neutrophils and T cells play a role in host immunity, these data suggest that CAR may be ideally positioned to modulate the immune response from the epithelial or endothelial cell compartments. (Morton et al 2016). CAR expression and infectivity with adenovirus (Ad) are increased in cystic fibrosis airway epithelial cells (Sharma et al. 2017). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| COVID-19 research v0.347 | PDGFRA | Alison Coffey commented on gene: PDGFRA: Evidence Summary from Illumina curation team: The PDGFRA gene encodes the platelet-derived growth factor receptor alpha protein, a tyrosine-protein kinase that acts as a cell-surface receptor for PDGFA, PDGFB and PDGFC, binding of which leads to the activation of several signaling cascades, and plays an essential role in the regulation of embryonic development, cell proliferation, survival and chemotaxis. PDGFRA has been demonstrated to be a critical receptor for human cytomegalovirus infection (PMID 18701889: Soroceanu et al. 2008). Di Pasquale et al. (2003) (PMID 14502277). also confirmed the role of PDGFRA and PDGFRB as receptors for adeno-associated virus type 5 (AAV-5). PMID 18701889: Soroceanu et al. 2008 - PDGFRA is specifically phosphorylated by both laboratory and clinical isolates of human cytomegalovirus (CMV) in various human cell types, resulting in activation of the phosphoinositide-3-kinase signaling pathway. Cells in which PDGFRA was genetically deleted or functionally blocked were nonpermissive to human CMV entry, viral gene expression, or infectious virus production. Reintroducing the human PDGFRA gene into knockout cells restored susceptibility to viral entry and essential viral gene expression. Blockade of receptor function with a humanized PDGFRA blocking antibody (IMC-3G3) or targeted inhibition of its kinase activity with a small molecule (Gleevec) completely inhibited human CMV viral internalization and gene expression in human epithelial, endothelial, and fibroblast cells. Viral entry in cells harboring endogenous PDGFRA was competitively inhibited by pretreatment with PDGF-AA. It was demonstrated that human CMV glycoprotein B directly interacts with PDGFRA, resulting in receptor tyrosine phosphorylation, and that glycoprotein B neutralizing antibodies inhibit human CMV-induced PDGFRA phosphorylation. The authors concluded that PDGFRA is a critical receptor required for human CMV infection, and thus a target for novel antiviral therapies. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Studies have demonstrated that CLDN9 and CLDN6 mediate the entry of the hepatitis C virus (HCV) into both hepatic and non-hepatic cell lines (Zheng et al. 2007) however, HCV infection is not dependent on the presence of CLDN9 (Fofana et al. 2013). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

ACMG/AMP-based pathogenicity criteria were applied. Modelling the ″COVID-resistant ″ state where pathogenic alleles would be beneficial, nine null alleles met PVS1. Thirty-seven variants met PM1 based on critical location +/-PP3 based on computational modelling. Modelling a ″COVID-susceptible ″ state, 31 variants in four upstream open reading frames and 5′ untranslated regions could meet PM1, and may have differential effects if aminoglycoside antibiotics were prescribed for pneumonia and sepsis. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Sarah Leigh Added comment: Comment on list classification: PMID 3208230 outlines the role of neutrophil extracellular traps (NETs) in the control of some pathogens including viruses, by virus capture and neutralization. In vivo treatment of the mice with DNase resulted in the enhanced susceptibility of IFNAR-/- mice to the CHIKV virus. Furthermore, the levels of MPO-DNA complex in acutely CHIKV-infected patients, were correlated with the levels of NETs and the viral load in the blood, suggesting that NETs are also released in natural human infection cases. Therefore, variants that result in myeloperoxidase deficiency, may well contribute to an increased susceptiblity to viral infection. At least 9 variants have been reported in Myeloperoxidase deficiency 254600 and these could well be contributing to increased viral susceptibily. |

Comments from Abdelazeem Elhabyan: GenBank - https://www.ncbi.nlm.nih.gov/gene?term=(human%5BOrganism%5D)%20AND%20TMEM173%5BGene%20Name%5D) This gene encodes a five transmembrane protein that functions as a major regulator of the innate immune response to viral and bacterial infections. The encoded protein is a pattern recognition receptor that detects cytosolic nucleic acids and transmits signals that activate type I interferon responses. Hypothesis: This gene is involved in interferon 1 pathway which is directly related to viral innate immune response. Upregulation may be associated with a protective effect or autoinflammatory response with aggravating effect. This is to be determined by clinical trials.
