RESUMEN
BACKGROUND AND AIMS: The fatty acid-binding proteins (FABPs) gene polymorphisms are related to several metabolic properties. We investigated the association of SNPs rs2241883 of FABP 1 gene with obesity to evaluate the role of FABP1 gene in the pathogenesis of obesity in the population of MASHAD study cohort. METHODS: In this cross-sectional study, 2731 individuals (1883 Obese and 848 nonobese) aged 35 to 65 years old, were enrolled from the Mashhad Stroke and Heart Atherosclerotic Disorder (MASHAD) study cohort. DNA Quantitation was determined using the NanoDrop®-1000 instrument (NanoDrop-Technologies). The rs2241883 polymorphisms were genotyped by double ARMs PCR (double amplification refractory mutation system) reactions. Data analysis was carried out using SPSS 22 and a p < 0.05 was set for statistical significance. RESULTS: The results showed that after adjusting for confounding factors, subjects having the CC genotype for rs2241883 polymorphism were at a higher risk of BMI ≥ 30 mg/kg2 with OR of 1.79 (CI = 1.05-3.07; p = 0.03) and 1.76 (CI = 1.04-2.99; p = 0.04) comparing with reference group using codominant and dominant models, respectively. CONCLUSION: The results showed that CC genotype for rs2241883 polymorphism is related to an increased risk of the obesity in dominant and codominant models in a population of MASHAD study cohort.
