摘要目的检测先天性心脏病患儿的22q11微缺失情况.方法采用商品化的多重连接依赖探针扩增(Multiplex ligation dependent probe amplification,MLPA)P250试剂盒,检测100例散发的先天性心脏畸形样本,其中40例产前超声诊断为心脏畸形的胎儿,60例为先天性心脏病患儿.结果心脏畸形的胎儿有2例为22q11微缺失,先天性心脏病患儿有1例22q11微缺失;3例检测出22q11微缺失的患儿,2例为3M典型缺失,1例为非典型缺失.结论在先天性心脏病患儿中存在22q11微缺失.

abstractsObjective To detect 22q11 microdeletion in the children and fetuses affected by congenital heart defects.Method MLPA P250 kit was used to detect 22q1 1 microdeletion in 100 cases of sporadic congenital heart defects including 40 fetuses and 60 patients diagnosed by ultrasound.Result Two cases from the fetuses and 4 case from the patients were found to have 22q11 microdeletion.Conclusion Three cases had 22q11 microdeletion in the congenital heart defects.
