CCR5 and COVID-19: We hypothesized that common variants at 3p21.31 may act as risk factors of severe COVID-19 by affecting the expression of CCR5. Combining public GWAS data with eQTLs data from the GTEx project, we have demonstrated that the minor allele of the rs35951367 SNP confers risk of severe COVID-19 and correlates with a lower expression of CCR5 in lung.
