| COVID-19 research v1.54 | IFNG | Sarah Leigh Added comment: Comment on list classification: Associated with relevant phenotype in OMIM, but not associated with phenotype in Gen2Phen. Two promoter variants are associated with viral susceptibility and response to therapy; c.-179G>T (RCV000015845.26) with accelerated progression to AIDS (PMID 12854077) and c.-764C>G (rs2069707) with enhanced promoter activity and increased viral clearance and treatment response in hepatitis C virus infection (PMID 17215375). The A allele of rs2430561 is associate with susceptibility to Hepatitis B virus infection (PMID 26458193). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

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. They noted that the SNP is present in 4% of African Americans and in only 0.02% of European Americans. PMID: 26458193 Wei et al. (2017) Eleven independent case-control studies were selected for the meta-analysis, comprising a total of 1527 HBV cases and 1467 healthy subjects. carriers of the IFN-γ A allele were more likely to develop HBV infection than those without in all five genetic models (all p < 0.05). According to the ethnicity-based sub-group analysis, a significant difference of the IFN-γ rs2430561 T > A (IFN-γ +874T/A) polymorphism was detected associated with the increased risk of HBV infection in Asians and European-derived populations in the majority of the groups. ; to: IFNG was identified through an OMIM search for potential viral susceptibility genes.

| COVID-19 research v0.347 | ATG5 | Alison Coffey commented on gene: ATG5: Evidence Summary from Illumina curation team: The ATG5 gene encodes a core autophagy protein which forms a complex with ATG12 and ATG16L that is important for autophagophore elongation. Autophagy plays a key antiviral role in various human infections by modulating different aspects of the immune response (Reviewed Tao et al. 2020; Ahmed et al.2018). ATG5 may play a role in cytokine regulation, in vitro, ATG5 depleted primary human blood macrophages produced lower levels of CXCL10 and IFNa when infected with influenza A virus (Law et al. 2007). ATG5 deficient mice also show reduced Ifn and Il22 secretion when infected with the single stranded RNA vesicular stomatitis virus (VSV) (Lee et al. 2007). Using a mouse model with a conditional depletion of ATG5 within dendritic cells, Lee et al. 2010 showed that ATG5 is required for antigen presentation by dendritic cells, as a result of reduced MHC-II antigen presentation, these mice, when intradermally injected with HSV-1, showed significantly lower IFNgamma production by CD4+ T cells. (Lee et al., 2010). The ATG5 complex is targeted by some viruses to enhance infection, for example, the foot and mouth disease virus (FMDV) targets the ATG5-ATG12 complex for degradation through its viral protein 3Cpro, similarly, depletion of ATG5 and ATG12 in vitro, by siRNA increased susceptibility to FMDV infection by reducing activation of the NF-?B and IRF3 pathways (Fan et al 2017). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
