TaqI polymorphism of the VDR gene: aspects related to the clinical behavior of COVID-19 in Cuban patients.

Purpose: To determine the relationship between the genotypes of the TaqI polymorphism of gene and the clinical forms of COVID-19 in Cuban patients.

Methods: TaqI polymorphism was determined by the PCR in 104 Cuban patients, who suffered different clinical forms of COVID-19.

Results: There was a greater possibility of presenting symptomatic forms [OR = 2.
