ACE2 and COVID-19: Analysis revealed statistically significant differences in the genotype and allele frequencies of the ACE2 rs2074192 polymorphism between the study groups (COVID-19 patients with MAFLD, COVID-19 patients without MAFLD, and controls) and the European reference population (χ2 = 16.86, df = 4, p < 0.001 for genotype; Fisher’s exact test, p < 0.001 for allele).
