摘要：Objective To investigate the association of the rs10885122G>T polymorphism in the ADRA2A gene in a Euro-Brazilian sample of healthy (controls) and type 2 diabetic (T2D) subjects. Subjects and methods We used fluorescent probes (TaqMan) to genotype 241 subjects, that is, 121 healthy and 120 T2D subjects, who were classified based on the Brazilian Diabetes Association (2013) and American Diabetes Association (2014) criteria. Results The genotype and allele frequencies showed no significant (P > 0.05) difference between the two studied groups. The minor allele (T) frequencies (95%CI) for rs10885122 were 19% (14-24%) and 20% (15-26%) for healthy and T2D groups, respectively. Carriers of the T allele (genotypes GT+TT) were significantly associated (P = 0.016) with approximately a 7-kg body weight reduction compared with the genotype GG, which was only found in the T2D group. Conclusion The rs10885122G>T polymorphism of the ADRA2A gene was not associated with T2D in Euro-Brazilians, and carriers of the T allele had lower body weight in the presence of T2D.
