Abstract
Chromosomal mosaicism is difficult to detect in prenatal diagnosis, and it seems even more difficult to predict its significance correctly. We present a case, in which G-trisomy mosaicism was diagnosed prenatally but was not verified in the aborted fetus. A practical approach to suspected fetal mosaicism in prenatal diagnosis is proposed.
摘要
染色体嵌合现象在产前诊断中很难被检测到，而且要正确预测其意义似乎更加困难。我们报告一例病例，其中产前诊断出G三体嵌合现象，但在流产胎儿中未得到证实。本文提出了一种针对产前诊断中疑似胎儿嵌合现象的实用方法。
