Abstract
A 29-year-old pregnant patient, gravida 4, para 3, sought genetic counseling because of a daughter who had Down's syndrome. Amniotic fluid obtained by amniocentesis indicated the fetal karyotype to be 47,XXX. The pregnancy was terminated and the karyotype was confirmed by typing venous blood from the fetus and the finding of double Barr bodies in the histologic sections of fetal tissue.
摘要
一名29岁、孕4产3的孕妇因女儿患有唐氏综合征前来寻求遗传咨询。通过羊膜穿刺术获取的羊水显示胎儿核型为47,XXX。终止妊娠后，通过对胎儿静脉血进行分型以及在胎儿组织的组织学切片中发现双巴氏小体，证实了核型。
