Autoradiographic demonstration of 3H-hypoxanthine incorporation in small numbers of amniotic fluid cells cultured on coverslips is a rapid and practical technique in the prenatal diagnosis of the Lesch-Nyhan mutation. An affected male fetus, a normal male fetus, and a heterozygous female fetus were identified within 14 days after amniocentesis in three pregancies at risk for the Lesch-Nyhan syndrome.
通过放射自显影法证明在盖玻片上培养的少量羊水细胞中掺入3H-次黄嘌呤,是产前诊断莱施-奈恩突变的一种快速且实用的技术。在3例有莱施-奈恩综合征风险的妊娠中,羊膜穿刺术后14天内就鉴定出了1例患病男胎、1例正常男胎和1例杂合子女胎。
