Regarding the relation of CDKN2B-AS1 (rs1333049) genotype distribution in moderate COVID-19 patients, there was a significant association of lower platelet count (P < 0.001), lower Hb (P = 0.012), higher CRP (P = 0.048) and higher ferritin (P = 0.019) in G/C and C/C genotypes compared to the G/G genotype. Here, GSTM1 is linked to COVID-19.
