Abstract
The author presents a new case of trisomy 20 mosaicism in an amniotic fluid culture and emphasizes the special aspects of this chromosomal abnormality. The prenatal diagnosis of "pseudo-mosaicism" is easier when in situ culture techniques are used. Controls of the results on a new sample of amniotic fluid and/or on foetal blood are useful to reinforce the diagnosis and to allow pregnancy to be continued.
摘要
作者报告了一例羊水培养中20三体嵌合体的新病例，并强调了这种染色体异常的特殊方面。采用原位培养技术时，“假嵌合体”的产前诊断更容易。对新的羊水样本和/或胎儿血液的结果进行对照，有助于加强诊断并使妊娠得以继续。
