It is the main point to focus on the elucidating of the pathogenesis of PNC as a polygenetic inheritance tumor, primarily establishing of the concept of susceptibility gene groups in NPC and the carcinogenesis model of the multi-step Domino effect involved in the molecular mechanisms of NPC dominated by susceptibility gene groups in order to lay out a substantial foundation for finding the high-risk susceptibility factors of NPC, screening the high-risk population of NPC and exploring the targetic and individual measures in diagnosis and treatment of NPC.

现主要阐述鼻咽癌作为一种多基因遗传性肿瘤的病因发病机制，初步建立鼻咽癌易感基因群的概念和鼻咽癌发生发展过程中易感基因群主导的多阶段性多米诺骨牌效应分子机制假说，为寻找鼻咽癌遗传易感风险因子，筛选鼻咽癌高危人群以及探索鼻咽癌靶向性及个体化的诊断和治疗手段奠定实验与理论基础。

Objective: Presymptomatic gene diagnosis of autosomal dominant polycystic kidney disease families by PCR Methods: Genomic DNA were extracted Highly polymorphic microsatellite markers(SM7, AG2 5, KG8, CW2) linked to the PKD1were amplified using PCR Ten ADPKD families (104 members,including 28 affected) were analysed Results: Nine children were diagnosed with presymptomatic gene diagnosis ,although all children presented a negative ultrasonic diagnosis Conclusion: The presymptomatic gene diagnosis ...

目的：应用PCR方法对常染色体显性遗传性多囊肾病家系进行症前基因诊断。方法：用PCR扩增与PKD1位点连锁的的高度多态性的微小卫星体DNA（SM7，AC2.5，KG8，CW2）为遗传标记，对10个ADPKD家系的104个成员（包括28个患者）找出染色体上与疾病连锁的单体型，进行连锁分析。结果：对9个无临床症状，且B超检查呈阴性结果的儿童做出了症前基因诊断。结论：能够应用PCR方法对ADP－KD家系成员快速、准确地做出基因诊断
