本文对 2 36例先天智能发育不全的患儿进行了染色体分析 ,检出异常核型 94例 ,检出率为 39 83% ,其中常染色体数目异常 80例 (33 90 % ) ,常染色体结构异常 7例 (2 97% ) ,性染色体数目异常 7例 (2 97% ) ,提示先天智能发育不全与染色体异常密切相关。
Chromosome analysis was performed in 236 cases of congenital hypoplasia in children. There were 94 cases of abnormal karyotype detected in 39 83% of cases, including 80 cases (33.9%) with autosomal abnormalities, abnormal autosomal structure 7 cases (2 97%), 7 cases of chromosomal abnormalities (2 97%), suggesting that congenital hypogenesis and chromosomal abnormalities are closely related.
