摘要
应用连锁分析法检测了6个鼻咽癌高发家系中HLA-[A-B]单倍型(haplotype).其中4个家系鼻咽癌者18人,接受检查10人,均属HLA-[A2-B46]单倍型,即A2和B46在同一条染色体上。在一个大家系,第Ⅱ、Ⅲ两代血缘亲属21人中有患者11人,受检5人均具HLA-[A2-B46]单倍型。其中2人在确定此单倍型后半年和11个月才发生鼻咽癌。故认为HLA-[A2.B46]可能与鼻咽癌发生相关。通过家系HLA单倍型分析,有可能发现鼻咽癌的遗传易感个体。
Linkage analysis of HLA-[A-B] haplotype in six nasopharyngeal carcinoma(NPC)high risk families were performed,In four of these six families there were totally eighteen NPC patients,Ten of them bad been tested and all were proved to be HLA-[A2-B46] haplotype,i.e,the genes A2 and B46 were located in the same chromosome.In the second and third generations of a large family, eleven out of twenty one family members were NPC patients. Five of these patients were tested and were found to be HLA-[A2-B46] haplotype. It is worthy to note that in two of them the cancer developed half a year and eleven months after HLA typing respectively.It can be considered that HLA-[A2-B46] haplotype may be related to the genesis of NPC. By means of linkage analysis of HLA haplotype it may be possible to detect the NPC genetic susceptibility cases in NPC high risk families.
