摘要 目的了解维生素D受体基因FokⅠ多态性在蒙古族人群中的分布。方法应用聚合酶链反应-限制性片段长度多态性技术,分析506名内蒙古地区蒙古族人的维生素D受体FokⅠ基因座的基因型和等位基因的分布频率。结果维生素D受体基因型FF、Ff、ff在本研究人群的分布频率分别为31%、52%和17%。等位基因F占57%,f占43%。基因型频率分布符合Hardy-Weinberg平衡定律。结论中国蒙古族人群维生素D受体基因FokⅠ多态性分布频率有其自身的特点。 Objective To investigate the polymorphism distribution of vitamin D receptor (VDR) gene Fok Ⅰ in Mongolian population of China. Methods Polymerase chain reaction-restriction fragment length polymorphism ( PCR- RFLP) method was used to analyze three genotypes FF, Ff and ff in the start codon of VDR gene (Fok Ⅰ ) in unrehted normal healthy Mongolian individuals of China. Results In the population, we obtained the allelic frequencies of 57 % and 43 % for (F) and (f) allele and the percentage of genotypes FF, Ff and ff to be 31%, 52 %, and 17 % respectively. Conclusion The polymorphism frequency and distribution of this VDR gene Fok Ⅰ in Mongolian population of Offna exhibit its own characteristics.
