CCR5 and COVID-19: Notably, 14 of these genes were not nominated by the GTEx eQTL analysis but were associated in various T, B, natural killer (NK), and myeloid cell subsets (Figure 3), including several genes involved in leukocyte recruitment and migration such as CCR1, CCR2, CCR3, CCR5, and CXCR6. These results highlight the resolution gained by conducting cell-type-specific analyses into immune-cell-expressed genes that may be linked to the genetic factors underlying severe COVID-19.
