Abstract: Objective To study the relationship between vitamin D receptor gene polymorphisms and the hereditary susceptibility of vitamin D deficiency rickets. Methods PCR-RFLP analyzes the technology using the polymerase chain reaction-restrictive fragment length multi-state properties to examine 159 examples vitamins D deficiency rickets child and 78 examples normal children (comparison group ) the vitamin D accept or (VDR) the gene Bsm I spot multi-state properties , compared with two group of between, VDR gene and gene frequency. Results  Vitamin D deficiency rickets sickness and comparison group child’s VDR the gene Bsm I spot gene distribution frequency respectively is: BB (0%), Bb(15.7%), bb(84.3%) and BB(0%), Bb(11.5%), bb(88.5%), two group of between difference not remarkable statistics significance (P > 0.05); vitamin D deficiency rickets sickness and comparison group child’s VDR the gene Bsm I spot allele distribution frequency respectively is: B(7.9%), b(92.1%), with B(5.8%),b(94.2%) two group of between difference not remarkable statistics significance (P > 0.05) Conclusion VDR the gene Bsm I enzyme cuts the position spot the multi-state properties possibly to have nothing to do with the vitamin D deficiency rickets heredity easy perception .

摘要: 探讨维生素D受体基因多态性与维生素D缺乏性佝偻病(佝偻病)遗传易感性的关系。方法  应用聚合酶链反应-限制性片段长度多态性(PCR-RFLP )分析技术检测2003年10月至2004年10月159例佝偻病患儿和78名健康儿童(对照组)VDR基因BsmⅠ位点的多态性,比较两组之间VDR基因型和基因分布。结果  佝偻病患儿和对照组儿童的VDR基因Bsm I位点基因型分布分别为:BB(0%),Bb(15.7%),bb(84.3%)和BB(0%),Bb(11.5%),bb(88.5%),两组 间差异无统计学意义(P >0.05);佝偻病患儿和对照组儿童的VDR基因Bsm I位点等位基因分布分别为:B(7.9%),b(92.1%)和B(5.8%),b(94.2%), 两组间差异无统计学意义(P > 0.05)。结论 VDR基因BsmⅠ酶切位点的多态性与维生素D缺乏性佝偻病的遗传易感性相关关系尚须大样本进一步确定。
