摘要
目的评估中国人群肝豆状核变性(Wilson disease,WD)基因(WND)侧翼徽卫星DNA(STR)位点 D13S296的基因多态性及在WD基因诊断中的价值。方法采用聚合酶链反应(PCR)、变性聚丙烯酰胺凝胶电泳 和银染法分析98名无血缘关系中国人D13S296的片段长度多态性;并对19个WD家系进行STR连锁分析。结果 D13S296有18个等位片段,长度范围为106-140bp,多态信息含量(PIC)为0.906。共检出8例症状前患者,10例 基因携带者及14例正常人,4例未能确定,基因诊断率达88.87%。结论 D13S296在中国人群是优秀的多态性标 记,对WD基因诊断有重要价值。
Objective To investigate the polymorphism of the short tandem repeat (STR) locus,D13S296, which locating in flank of wilson disease(WD) gene (WND),and use it in gene diagnosis in WD. Methods The alleles of D13S296 were analyzed by using polymerase chain reaction (PCR), polyacrylamide gel electrophoresis (PAGE) and silver staining in 98 unrelated Chinese. Take STR linkage analysis in 19 WD families. Results in Chinese, D13S296 included 18 alleles, and the alleic size were 106 ~ 140bp, polymorphism information content (PIC) was 0.907. In 109 individuals of 19 WD families,we founded 8 presymptomatic patients, 10 carriers, 14 normal people,4 could not determined,the rate of gene diagnosis was 88. 87 %. Conclusion D13S296 was an excellent polymorphism marker in Chinese and was very important in gene diagnosis of WD.
