Table I. COVID-19 patient survival according to the rs17775810 genotype (TT versus non-TT) in 688 UKB subjects. The effect of genotype on survival was significant (p=0.036, 2 tailed Fisher exact test). The TT homozygotes had the lowest death rate (0%), whereas the non-TT genotypes (i.e. CT and CC) had the highest death rate (16.2%).
