Abstract
Background
Overweight is the scourge of modern society and a major risk factor for many diseases. For this reason, understanding the genetic component predisposing to high body mass index (BMI) seems to be an important task along with preventive measures aimed at improving eating behavior and increasing physical activity.
Methods
We analyzed genetic data of a European cohort (n = 21,080, 47.25% women, East Slavs ancestry >80%) for 5 frequently found genes in the context of association with obesity: IPX3 (rs3751723), MC4R (rs17782313), TMEM18 (rs6548238), PPARG (rs1801282) and FTO (rs9939609).
Results
Our study revealed significant associations of FTO (rs9939609) (β = 0.37 (kg/m2)/allele, p = <2 × 10−16), MC4R (rs17782313) (β = 0.28 (kg/m2)/allele, p = 5.79 × 10−9), TMEM18 (rs6548238) (β = 0.29 (kg/m2)/allele, p = 2.43 × 10−8) with BMI and risk of obesity.
Conclusions
The results confirm the contribution of FTO, M4CR, and TMEM18 genes to the mechanism of body weight regulation and control.
