摘要 东南亚各国和我国长江以南各省区人群中东南亚缺失型(- -^SEA)α地中海贫血(地贫)基因携带率高达4%~14%^1.2。- -^SEA、自身或与α地贫2(-α,如-α^3.7和-α^4.2)或非缺失型(α^T)α地贫相互组合可分别引起致死的Hb Bart’s 水肿综合征和严重影响生命质量的HbH病。目前对该病尚无根本有效的治疗方法,通过遗传筛查和产前诊断选择性地淘汰重型α地贫胎儿是控制该病发生的唯一途径,其中- -^SEA携带者的峪定则是关键的一步?我们采用单管多重PCR(gap—PCR)技术作为标准并辅以铁代谢状态的分析,对酶联免疫吸附试验(ELISA)检测外周血红细胞中ζ珠蛋白链作为临床- -^SEA携带者的常规筛查方法进行了评价,以期为该型α地贫的大样本人群筛查提供新的技术选择。
