LZTFL1 and COVID-19: Bivariate analysis between the genetic polymorphisms and COVID-19 severity revealed a statistically significant association between the LZTFL1 rs11385942 polymorphism with severe COVID-19 and severe COVID-19 requiring hospitalization in ICU (p = 0.01; OR = 5.73; 95% CI = 1.24–26.46 and p = 0.02; OR = 6.12; 95% CI = 1.14–32.63, respectively, under the allelic genetic model).
