Likewise, for the COVID-19 genes, the expression profiles in the different tissues (Figure S4) showed that the HLA-DRB1, LAMP2 and PLSCR1 genes were more expressed in the adipose tissues; HLA-DRB1, LAMP2, PLEKHA4, PLSCR1, RAVER1, TES and THBS3 genes were more represented in tissues of the circulatory system, especially in arteries and HLA-DRB1, HLA-DQA1, IFNAR2, OAS1, RAVER1, TES and TYK2 genes were more represented in tissues of the immune system. The gene discussed is IFNAR2; the disease is COVID-19.
