摘要
目的 了解东莞地区新生儿α-地中海贫血发病率。方法 利用PCR法对 1378例新生儿脐血 ,进行α -地中海贫血的筛查。结果 1378例脐血筛查中 ,有 36例为右侧缺失杂合子 (-αα3 .7/αα) ,9例为左侧缺失杂合子 (-αα4.2 /αα) ,发病率分别为 2 .6 1%和 0 .6 5 %。结论 该法快速、准确 ,可作为常规方法用于临床样品的分子筛查。
Objective: To understands the incidence rates of alpha-thalassemia in Dongguan newborns. Methods: Using PCR-based method to screen alpha-thalassemia genotypes in 1378 newborns in Dongguan. Results of 1378 newborns, the αα 3.7/αα-thalassemia was detected in 36(2.61%) of the newborns, αα 4.2/αα-thalassemia in 9(0.65%) cases.
