摘要:

背景:研究表明骨形态发生蛋白7基因定位的染色体20q13是肥胖的易感区域,功能与基因定位均表明骨形态发生蛋白7基因是肥胖的易感基因。
目的:探讨骨形态发生蛋白7基因变异与新疆维吾尔族肥胖人群的关系。 
方法:以流行病学调查为基础的病例-对照研究,选取1 063例维吾尔族人群作为研究对象。先在48例维吾尔族肥胖人群(男/女:24/24)中测序筛查骨形态发生蛋白7基因功能区的变异位点,选取代表性变异位点应用TaqMan-PCR技术在研究人群中进行基因型鉴定并开展病例-对照关联研究。 
结果与结论:在骨形态发生蛋白7基因的功能区共发现5个新的和8个已知的变异位点。骨形态发生蛋白7基因的2个代表性变异位点rs60254222和rs17480735均符合Hardy-Weinberg平衡。老年人群中rs60254222变异的AA、AG、GG基因型在肥胖组及正常对照组中的频率分布分别为32.2%,55.7%,12.2%和23.8%,48.3%,27.9%,且两组间频率分布差异有显著性意义(P < 0.01)。老年人群中rs60254222变异不同基因型组间体质量指数、腰围、腰臀比差异有显著性意义(P < 0.05)。Logistic分析提示老年人群中rs60254222变异GG基因型是肥胖的保护性因素(OR=0.578,95%可信区间为0.401~0.833,P=0.003)。结果表明骨形态发生蛋白7基因变异位点rs60254222可能与新疆维吾尔族人群肥胖相关。

Abstract:

BACKGROUND: Studies show that bone morphogenetic protein 7 (BMP-7) gene maps to chromosome 20q13, a susceptibility locus for obesity. BMP-7 represents a strong biological and positional candidate for a susceptibility factor for obesity.
OBJECTIVE: To investigate the association between the genetic variations of functional region in BMP-7 gene and obesity in Xinjiang Uygur populations.
METHODS: A case-control study was conducted based on epidemiological investigation. 1063 Uygur populations were selected. The exons, segmental introns and the promoter regions of BMP-7 gene were sequenced in 48 Uygur obese patients (male/female: 24/24). Representative variations were selected according to the minor allele frequency and linkage disequilibrium and genotyped using the TaqMan polymerase chain reaction method in 1063 Uygur individuals, a relatively isolated general population in a relatively homogeneous environment and a case-control study was conducted to analyze the association between genetic variations of BMP-7 gene and obesity.
RSSULTS AND CONCLUSION: Five novel and eight known variations in the BMP-7 gene were identified. Two genotype distributions, rs60254222 and rs17480735, followed Hardy-Weinberg equilibrium. There were significant differences in AA, AG, GG genotype distribution frequency of rs6025422 variation between obese and control groups in old adults (32.2%, 55.7%, 12.2% vs. 23.8%, 48.3%, 27.9%; P < 0.01).There were significant differences in means of body mass index, waist circumference and waist-to-hip ratio were significantly decreased among individuals with AA, AG and GG genotypes of rs60254222 in old adults (P < 0.05). Logistic regression analysis showed that GG genotype of rs60254222 variation might be a obesity protective factor in old adults (OR = 0.578, 95% confidence interval 0.401-0.833, P = 0.003). Results showed that rs60254222 polymorphism in BMP-7 gene may be associated with obesity in Uygur populations.
