①Location of WD gene in Ch inese: Using pairwise linkage analysis and multipoint linkage analysis method, w e constructed a genetic map of DNA markers within D13q14.2-3 which refined the location of WD gene by restriction fragment length polymorphism and microsatellite polymorphism analysis;②Screen for mutations of WD gene in Chinese people: we detected the structure of 21 exons of WD ge ne in 45 patients from 39 pedigrees by PCR-SSCP(Single strand conformation poly morphism) and PCR-DNA sequencing technology, found a new mutation in exon 5 and nuclcotide sequence analysis showed it is a T insertion. We also conformed the Arg778Leu in exon 8, the highest frequence mutation point in Chinese people, wit h mutation rate 22.8%in total;③Carrier detection and presymptomatic diagnosi s of WD: Based on DNA recombination technology, we peformed successfully the gen e diagnosis in all individuals of 79 families with WD and built up a helpful spe cific enzyme cut method (PCR-Msp1) to detect the carrier and presympomatic patients in Chinese pe ople with WD.

①WD的基因定位研究：通过RFLP及微卫星多态性分析，应用两位点及多位点连锁软件，建立了中国人WD基因在D13q14.2-3区域的精细遗传连锁图谱，从而首次对中国人WD基因进行了精确定位；②WD基因突变研究：应用PCR-SSCP及DNA测序技术，对39个家系45名WD患者进行该致病基因的21个外显子突变筛选，发现WD基因5号外显子存在新的T插入突变，并证实中国人WD基因的突变热点为8号外显子，突变形式为Arg778Leu，其频率为22.8%；③WD的症状前诊断和杂合子检出：应用DNA重组技术对79个家系进行基因诊断，成功地进行了WD的症状前诊断和杂合子检出，并建立了WD的基因筛选的PCR-Msp 1酶切方法。
