Abstract:
Objective To analyze the association between the genetic variations of functional region in bone morphogenetic protein ( BMP7 ) gene and dyslipidemia in Chinese Uygur individuals. Methods The case-control study was conducted in 1514 Uygur Chinese based on epidemiological investigation. The all exons, segmental introns and the promoter regions of BMP7 gene were sequenced in 48 out of 1514 Uygur Chinese. Representative variations were then selected according to the minor allele frequency (MAF) and linkage disequilibrium, and genotyped using the TaqMan polymerase chain reaction method in 1514 Uygur Chinese, a relatively isolated general population in a relatively homogeneous environment, to observe the association between genetic variations of BMP7 gene and dyslipidemia. Results Five novel and eight known variations in the BMP7 gene were identified. All genotype distributions were tested for deviations from HardyWeinberg equilibrium. There were significant differences of genotype distribution of rs6025422 between hypertriglyceridemia group and control group ( P = 0. 001 ). The levels of triglyceride (TG) showed a decreasing teadency in individuals with AA, AG and GG genotypes of rs6025422. Odd ratio (OR) value adjusted for age, gender, body mass index, smoking and alcohol drinking habits was 0. 562 by logistic regression analysis (95% CI: 0. 393 - 0. 802, P = 0. 002 ). Concluslon The present study shows rs6025422 polymorphism in the BMP7 gene is linked with hypertriglyceridemia phenotype in Uygur Chinese population.
