rs13050728 was associated with tryptase gamma 1 (TPSG1, P= 1.5×10-5) and vascular endothelial growth factor 2 (VEGFR2, P= 2.6×10-5, Supplementary Table 12), and both showed strong evidence of colocalization with COVID-19 hospitalization (PP.H4=0.96 for VEGFR2, PP.H4=0.96 for TPSG1, Figure 4). Here, TPSG1 is linked to COVID-19.
