Bar graphs depicting Minor allele frequency, Odds ratio, correlation and CT images in the study group (A) Minor allele Frequency (MAF) in Controls, asymptomatic, mild-to-moderate and severe patients. Decreasing trend was noted in MAF with increasing severity (B) MAF and Odds ratio (Dominant and Recessive Models) in Asymptomatic, Mild-to-moderate and Severe COVID19 patients. An inverse trend was seen between risk for severity and MAF. Green bars depict Minor allele frequency, Blue bars depict Odds ratio (Dominant Model) and Yellow bars depict Odds ratio (Recessive Model). Green colour dotted line depicts Linear for MAF, blue colour dotted line depicts Linear for Odds ratio (Dominant Model) and Yellow colour dotted line depicts Linear for Odds ratio (Recessive model) (C) A negative correlation (Pearson's correlation coefficient; r = −0·76) was seen between MAF and mortality rates (D and E) Representative CT images of a patient with mild symptoms with genotype GA and AA(variant), (F) severe disease with GG genotype (wild).
