Association between peroxisome proliferator-activated receptor gamma coactivator-1 alpha polymorphism and hypertension in Mongolians in Inner Mongolia

Abstract

We investigated a possible association of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α) Gly482Ser polymorphism with hypertension in Mongolians in Inner Mongolia. A total of 787 subjects were enrolled randomly, including 390 hypertension patients and 397 healthy controls. Triglycerides, cholesterol, and fasting plasma glucose were measured, and body mass index was calculated. PCR-RFLP was used to analyze Gly482Ser polymorphisms. There were significant differences in triglycerides, fasting plasma glucose, and body mass index between hypertension patients and healthy controls. Cholesterol levels did not differ significantly. The PGC-1α gene GG, GA and AA genotype distributions were 37.2, 48.5 and 14.4%, respectively, in patients and 48.6, 37.3 and 14.1% in healthy controls. The frequencies of PGC-1α genotype GA and allele A were significantly different between hypertension patients and healthy Mongolians. We concluded that PGC-1α Gly482Ser polymorphism is associated with hypertension in Mongolians in Inner Mongolia.
