摘要 目的探讨维吾尔族和汉族儿童δ-氨基-γ-酮戊酸脱水酶(ALAD)基因多态性及其与铅中毒遗传易感性的关系。方法PCR-RFLP方法对新疆乌鲁木齐市的维吾尔族443名和汉族469名儿童ALAD基因多态性进行分析。应用单因素和多因素分析探讨了维吾尔族和汉族儿童ALAD基因多态性与血铅水平的关系,及影响血铅水平的因素。结果在维吾尔族人群中,ALAD1和ALAD2等位基因频率分别为90.52%和9.48%;在汉族人群中,ALAD1和ALAD2等位基因频率分别为95.73%和4.27%;两者差异有统计学意义(P<0.01)。维族儿童血铅浓度为(55.86±2.23)μg/L,铅中毒流行率为23.25%;汉族儿童血铅浓度为(53.05±2.24)μg/L,铅中毒的流行率为23.31%,两民族血铅水平和铅中毒流行率之间均无统计学意义(P>0.05)。结论维吾尔族和汉族儿童ALAD基因多态性与血铅水平间无相关关系。
