In the present study, the frequencies of alleles G and C in the study population were 74.1% and 25.9%, respectively.Other studies have also demonstrated a predominance of theancestral allele (G) ranging from 60% to 70%.28Furthermore,we observed a higher frequency of GG genotype (56%), fol-lowed by GC (36.2%) and CC (7.8%). This is consistent withthe aforementioned studies
