Association study of Apolipoprotein A5 gene (APOA5 gene) variant with the metabolic syndrome in local Pakistani population

OBJECTIVE

To explore the association of rs662799 variants of Apolipoprotein A5 gene with metabolic syndrome in Pakistani population.

METHODS

The case-control study was conducted at Pakistan Institute of Medical Sciences, Islamabad, Pakistan from 2014 to2016, and comprised subjects enrolled from the out-patient clinics. Groups were formed on the basis of preliminary screening for risk factors like obesity, insulin resistance, hypertension, dyslipidemia and fasting blood glucose levels. Met S was diagnosed based on the international diabetes federation criteria. Blood samples were collected for biochemical testing and deoxyribonucleic acid extraction. Genotyping of rs662799 was performed a the Genome Research Centre of the University of Hong Kong using Sequenom Mass ARRAY, iPLEX Gold technology. Data was analysed using SPSS 16and Plink software.

RESULTS

:There were 712 subjects in two groups of 356(50%) each. The overall mean age was 41.59}7.18 years. There was a significant association of risk allele C of rs662799 with metabolic syndrome (p=0.002). The risk showed strong association with dyslipidaemia (p=0.03) and obesity (p=0.01) which are risk phenotypes of metabolic syndrome in age- and gender-adjusted model.

CONCLUSIONS

The association of risk allele C of genetic variant rs662799 of Apolipoprotein A5 gene with dyslipidaemia and obesity may lead to the development of metabolic syndrome in the Pakistan adult population.
