Functionally important genes for COVID-19 were prioritized by the SMR analysis using six eQTL and two mQTL datasets, which identified a total of 25 associations, involving seven protein-coding genes (TYK2, IFNAR2, OAS1, OAS3, XCR1, CCR5, and MAPT) and four non-coding genes (LRRC37A4P, IL10RB-AS1, MGC57346, and CCR5AS) (Table 2; Figure 1). Here, XCR1 is linked to COVID-19.
