Abstract
Several studies have shown that rs9939609 and rs1421085 in fat mass and obesity-associated
(FTO ) gene rs17782313 and rs12970134 in melanocortin-4 receptor (MC4R ) gene influence obesity. In the present study, we aimed to determine association
between rs9939609, rs1421085, rs17782313, and rs12970134 polymorphism, and their relation
with body mass index (BMI), glucose, insulin, homeostasis model assessment of insulin
resistance (HOMA-IR) and lipid values in obese children. We included 100 newly diagnosed
obese children and 100 healthy children. The rs1421085 (CC/CT) (p = 0.019) and rs9939609 (AA/AT) (p = 0.002) polymorphism regions were higher in the obese group. Additionally, we found
that both the rs1421085 (CC/CT) and rs9939609 (AA/AT) polymorphism associated with
high-density lipoprotein cholesterol (p = 0.011 and p = 0.003) and triglycerides (p = 0.01 and p = 0.004) level, respectively. Further, the rs9939609 and rs1421085 variants of FTO gene associated with HDL-cholesterol and triglycerides levels in obese children;
however, updated studies with a large sample size are required to establish strong
links with genetic variants and risk factors in childhood obesity.
