Method:G-banding was employed in karyotype analysis of patients with primary amenorrhea. Results:Karyotype analysis of 468 patients with primary amenorrhea revealed that 255 patients(54.49%) had normal female karyotypes and 213 patients(45.41%) had abnormal karyotypes,including 143 patients with abnormal X chromosome,4 patients with mosaic X-Y chromosome,57 patients with 46,XY karyotype,8 patients with abnormal autosome and one patient with X-autosome translocation.All primary amenorrhea patients with deletion or break-up in Xp11.1-11.4 were short in stature. Conclusion:One of the main reasons of primary amenorrhea was chromosome abnormalities,especially sex chromosome abnormalities.Karyotype analysis should be routinely applied to detect primary amenorrhea patients. Xp11-12 may be critical to development of stature.展开更多
目的:对1例X连锁隐性遗传鱼鳞病合并隐睾的患儿及其家系成员进行遗传学分析,探讨其致病原因。方法:对患儿及其家庭成员进行常规染色体G显带核型分析和低深度全基因组拷贝数变异测序分析(CNV-seq)。结果:染色体核型分析未见明显异常。CNV...目的:对1例X连锁隐性遗传鱼鳞病合并隐睾的患儿及其家系成员进行遗传学分析,探讨其致病原因。方法:对患儿及其家庭成员进行常规染色体G显带核型分析和低深度全基因组拷贝数变异测序分析(CNV-seq)。结果:染色体核型分析未见明显异常。CNV-seq检测发现患儿及哥哥和母亲的X染色体p22.33-p22.31处缺失5.28Mb区域,该片段包含Xp22.31 recurrent region (includes STS)全部。结论:患儿X染色体拷贝数变异遗传自其母亲,Xp22.31缺失是该患儿异常表型的遗传学病因。展开更多
