应用限制性内切酶酶谱和快速微量DNA分子杂交技术,对7例有Hb Bart’s水肿胎儿危险和1例有Hb H病胎儿危险的孕妇进行产前基因诊断,诊断结果5例胎儿正常,3例为Hb Bart’s水肿胎儿,与分娩及引产结果完全符合。
Prenatal genetic diagnosis was performed in 7 pregnant women with fetal Hb Bart’s edema and 1 pregnant woman with Hb H disease using restriction endonuclease digestion and rapid micro DNA molecular hybridization. The diagnostic results of 5 fetuses were normal, 3 Cases of Hb Bart’s edema fetus, and childbirth and abortion results in full compliance.
