Gene: CCR5
CCR5 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: Cytokine receptor. From OMIM: Variation in the CCR5 gene is associated with susceptibility to West Nile Virus (PMID 16230476;21935451;19247438). Numerous studies additionally demonstrate variation in CCR5 is associated with resistance / susceptibility to HIV and HBV infection. PMID 24098976: Zapata et al. (2013) - main genetic factor related to HIV-1 resistance is the CCR5-Δ32 variant. The CCR5-Δ32 variant along with SNPs in the CCR5 promoter and the CCR2-V64I variant have been included in seven human haplogroups (HH) previously associated with resistance/susceptibility to HIV-1 infection and different rates of AIDS progression. This study determined the association of the CCR5 promoter SNPs, the CCR5-Δ32 mutation, CCR2-V64I SNP, and HH frequencies with resistance/susceptibility to HIV-1 infection in a cohort of HIV-1-serodiscordant couples from Colombia. The CCR5-Δ32 allele is not responsible for HIV-1 resistance in this HESN group; however, the CCR2-I allele could be protective, while the 29G allele might increase the likelihood of acquiring HIV-1 infection. HHG1 and the AGACCAC-CCR2-I-CCR5 wild-type haplotype might promote HIV-1 infection while HHF2 might be related to resistance. PMID 31686727: Moudi et al. (2019) - study evaluated the association between the CCR5-Δ32, CCR5-2459A/G, MCP-1-2518A/G, VDR-APa1A/C, VDR-Taq1T/C SNPs and HBV susceptibility, in samples of Iranian populations. Significant associations with susceptibility to chronic HBV infection was observed with CCR5-2459A/G, MCP1-2518A/G, VDR-APa1A/C, VDR-Taq1T/C polymorphisms. In addition, no association of the CCR5D32 SNP with the disease was found. PMID:31100442 - Koor et al. (2019) - 9 CCR5 haplotypes are defined by seven 5'UTR SNPs in HIV-1 disease. Study identified key SNPs in HIV-1 control in both controllers and progressors.

Preprint https://doi.org/10.1101/2020.05.02.20084673 reports 10 terminally-ill, critical COVID-19 patients with profound elevation of plasma IL-6 and CCL5 (RANTES), decreased CD8+ T cell levels, and SARS-CoV-2 plasma viremia. Treatment with CCR5 blocking antibody leronlimab, results in complete CCR5 receptor occupancy on macrophage and T cells, rapid reduction of plasma IL-6, restoration of the CD4/CD8 ratio, and a significant decrease in SARS-CoV-2 plasma viremia. From single-cell RNA-sequencing, this effect appears to be a result of reduced transcriptomic myeloid cell clusters expressing IL-6 and interferon-related genes.Created: 11 May 2020, 3:21 p.m. | Last Modified: 11 May 2020, 3:21 p.m.
