Background: Obesity is a major risk factor of chronic-diseases, including cardiovascular-diseases (CVD). Increasing evidence is showing the association of heat-shock protein (HSP) with type-2 diabetes and CVD; however, there is little data on the relationship between the genetic-polymorphisms of HSP70-2 with obesity. Aim: The present study has investigated the association between 1267HSP70-2 genetic polymorphism and obesity in an Iranian population with 317 subjects. Subjects and methods: Anthropometric parameters and biochemical measurements were measured in all the samples, while genotypes were determined using PCR-RFLP. Univariate/multivariate analyses were conducted to explore the relationship between the genetic-polymorphisms and obesity. Results: The data showed a significant association between 1267HSP70-2 polymorphism in obese subjects, compared to the non-obese group. Moreover, it was observed that this polymorphism was associated with obesity in the CAD + group, which had a high BMI compared to non-obese controls. Conclusion: The 1267HSP70-2 polymorphism is associated with obesity in an Iranian population, supporting a possible potential genetic link between obesity and cardiovascular diseases.
