摘要: 本文从1992例遗传咨询病例中收集29例Y染色体异常的病例,其中Y染色体数
目异常(47,XYY)2例;Y染色体结构异常8例:Y/Y易位1例、Yp+3例、de l(Y)3例、嵌合
体dic(Y)1例;Y染色体长度变异19例。对Y染色体这几种异常类型的遗传效应进行分析。
Abstract:Twenty nine cases of Y chromosome abnormalities were found in 1992 patients asking genetic counseling.Different kinds of Y chromosome abnormalitics were detected by G and banding techniques.These were 47,XYY(2 cascs);46,X,del(Y)(3 cascs);46,X,Yp+(3 cases);46,X,t(Y;Y)(1 case);45,X/46,X,dic(Y)(1 case) and length changes of Y chromosome(19 cases).The genetic effects of Y chromosome abnormalities have been analyzed in this report.
