摘要
我院对几年来遗传咨询及住院疑有染色体异常者695例进行了染色体检查。检出异常核型70例,异常率10.1%。70例异常核型中常染色体异常48例,占异常核型的68.6%,性染色体异常22例,占异常核型的31.4%。异常核型涉及除5、10、12、17、19、20、22号以外的17条染色体,共计27种核型。本文对额外小染色体来源、携带者的表型及平衡易位是否产生遗传效应等进行了讨论。
A cytogenetics study has been performed in 618 cases suspectable having chromosome abnormalities during genetic counseltation and inpatient. We found that 24 structural aberration,29numerical aberration and 2 sex differentiation aberration. As well as male pseudohermaphroditism,were found case. So the abnomality rate is 8.2%. 38 cases has autosomal aberration and 18 cases has sex chromosome aberration. Karyotype aberration involves chromosome No:1、4、6、7、8、9、10、 13、 14、 22、X、Yetc , about 25 kinds of karyotype in total.
