To establish a method for the prenatal diagnosis of 22q11 microdeletion syndrome.
BACs-on-Beads (BoBs) and fluorescence in situ hybridization (FISH) were performed on a fetus for whom amniotic chromosomal culturing has failed and a pair of twin fetuses suspected for 22q11 deletion syndrome.
22q11 microdeletion was detected in all 3 fetuses by prenatal BoBs as well as FISH, with only one red signal detected at the DiGeorge/VCFS N25 site and two green signals on the 22q13.3 ARSA site.
The combination of prenatal BoBs and FISH can provide a method for the prenatal diagnosis of 22q11 microdeletion.
建立一种22q11微缺失综合征的产前诊断方法。
对羊水染色体培养失败的一名胎儿以及一对疑似22q11缺失综合征的双胎胎儿进行了芯片杂交技术(BoBs)和荧光原位杂交(FISH)检测。
通过产前BoBs和FISH检测,在所有3例胎儿中均检测到22q11微缺失,在DiGeorge/VCFS N25位点仅检测到一个红色信号,在22q13.3 ARSA位点检测到两个绿色信号。
产前BoBs和FISH联合应用可为22q11微缺失的产前诊断提供一种方法。
