用ＰＣＲ方法检测东南亚缺失型α－地贫１－－ＳＥＡ／αα基因的方法对６例α－地贫家系进行胎儿产前检测，结果：１例为Ｂａｒｔ水肿胎儿（死胎），１例为东南亚缺失型α－地贫１基因携带者，其余４例为α－地贫２携带者或正常胎儿。该法简洁、易行、准确性高，为α－地贫早期胎儿诊断及α基因的检测提供一种新方法。
Detection of 1-SEA / αα Gene in Deletion-type A-Thalassemia in Southeast Asia by PCR Method Six cases of α-thalassemia pedigree were tested prenatally. Results: 1 case was Bart edema (stillbirth) and 1 case was Southeast Asia Lack of α-thalassemia 1 gene carriers, and the remaining 4 cases of α-thalassemia 2 carriers or normal fetuses. The method is concise, easy and accurate. It provides a new method for the diagnosis of fetal α-thalassemia and detection of α-thalassemia.
