摘要
目的 :应用PCR 酶切法对中国人WD患者ATP7B基因的高频突变点进行检测 ,企图建立一种能应用于临床的中国人WD快速基因诊断方法。方法 :用限制性内切酶MaeⅡ对 48例患者及 30例正常人的ATP7B基因第 12外显子 935密码子PCR扩增后进行酶切分析。结论 :ATP7B基因第 12外显子 935密码子为中国人WD患者的高频突变点之一 ;PCR 酶切法可作为WD常用的基因诊断方法应用于症状前期患者的筛选及产前诊断。
Object:To detect high freqency mutation pint in Chinese patients with Wilson disease (WD)by PCR-augmentation and restriction-analysis and to establish a fast gene diagnosis method for WD. Methods:We screen the codon 935 of exon 12 in ATP7B gene of 48 WD patients and 30 controls by PCR-augmentation and restriction-analysis with restriction enzyme Mae Ⅱ.Result:The enzyme cut results of 935 codon sugested:no abnormal found in 30 controls .In 48 patients,we found 6 compound heterozygotes(22.5%),no homozygous was found.Conclusion:The codon 935 of exon 12 in ATP7B gene is one of the high frequency of mutation points in Chinese WD patients,PCR-augmentation and restriction-analysis is a fast gene diagnosis method for WD.
