Abstract

The 3p21.31 locus has been associated with severe COVID-19 prognosis in GWAS studies. Here, we evaluated whether three polymorphisms (LZTFL1 rs10490770, CXCR6 rs2234355 and rs2234358) in the reported locus were associated with the need for mechanical ventilation, hospitalization length and death in 102 COVID-19 hospitalized Brazilian subjects. No genetic association was found with the need for mechanical ventilation and hospitalization length. CXCR6 rs2234355 was associated with mortality under the codominance model, with carriers of the A/A genotype having a greater chance of death than A/G (OR: 10.5; 95% CI: 1.55-70.76). Our results further suggest that the CXCR6 genetic variant contributes to COVID-19 outcomes.
