Genetic Association of Apolipoprotein A5-1131T>C Polymorphism with Traits of Metabolic Syndrome

To investigate the association of -1131T>C polymorphism of apolipoprotein A5 (APOA5) with metabolic syndrome and associated traits. A cross-sectional comparative study. Department of Physiology, University of Health Sciences Lahore, from July 2016 to December 2017. Study population included 200 cases of metabolic syndrome and 200 controls. Cases were selected from Sheikh Zayed Hospital, Lahore according to the International Diabetes Federation guidelines. Fasting blood sample of 8 ml was taken for biochemical and genetic analysis, as per objective. Demographics, waist circumferance and blood pressure (BP) were also recorded. Subjects with metabolic syndrome had significantly higher waist circumference, BP, serum lipid and glycemic parameters as compared to the controls (pC genotype TT was 180 (45%), 202 (50.5%) for TC and 18 (4.5%) for CC. Minor C allele frequency of APOA5-1131T>C variant was significantly higher in metabolic syndrome as compared to the controls (0.33 vs. 0.26: p = 0.031*). In the Dominant genotype model (TC+CC vs. TT), 'TC+CC' genotype was significantly associated with the increased risk of metabolic syndrome (OR: 1.50, CI: 1.01-2.23, p = 0.044*). Waist circumference and fasting triglyceride levels were significantly higher in 'TC +CC' genotype as compared to the 'TT' in metabolic syndrome and controls (p = C with the increased risk of Met S and the association remained significant after controlling for age and gender.
