摘要/Abstract

摘要： 报告1例孕38周经剖腹产出生的畸形男儿。患儿双侧唇裂，严重腭裂，胸骨畸形，骶部脊柱裂，双侧睾丸未降，足内翻。出生后10分钟由于呼吸衰竭而夭折。患儿经外周血淋巴细胞染色体核型分析为47，XY,+13,后经荧光原位杂交技术加以证实。对患儿及其父母进行短重复序列D13S317位点检测，证实患儿额外的13号染色体源自父亲第一次减数分裂不分离。

关键词: D13S317位点, Patau综合症, 额外13号染色体

Abstract: A boy was born at 38 week’s gestation by Cesarean delivery . Affected newborn was characteristically bilateral cleft lip and severe cleft palate. The sternum was malformation. The sacrospinal bifida and the talipes varus were found and the testes were not descended. The boy died after delivery within 10 minutes owing to respiratory failure. Cytogenetic analysis of his peripheral lymphocyte by G banding showed a karyotype 47,XY,+13 , which was also confirmed by fluorescence in situ hybridization (FISH). The locus D13S317 was detected by the peripheral blood from the boy and the parents. Three alleles were found from the boy in locus D13S317 and two from the father. The extra chromosome 13 was from the nondisjunction during the first meiotic division of the father.
