Association of rs16953002 FTO Gene Polymorphism with Type 2 Diabetes and Obesity

Genome-wide association studies (GWAS) has identified that FTO gene polymorphisms was associated with the risk of type 2 diabetes and obesity. However, the findings in subsequent studies were inconsistent in various populations. This study aimed to investigate the association of FTO rs16953002 with type 2 diabetes and obesity in Yazd, Iran.
Methods & Materials: Unrelated study subject controls (n=200) and type 2 diabetes cases (T2DM) (n=200), were randomly selected from Yazd, Iran. Genotyping was done by the polymerase chain reaction-restriction fragment length polymorphism method. Age and gender, smoking, weight and body mass index (BMI) were analyzed using the analysis of χ2 test.
The rs16953002 A/G polymorphism of the FTO gene showed significant association with T2DM and obesity. The AG, GG genotypes were significantly higher in T2DM and obese subjects compared to the group subjects.
The result of the present study indicate that the genetic variant in FTO may contribute to T2DM and obesity risk in Yazd population.
