Abstract
The chromosome analysis in a 9 years-old boy showed the presence of three cell lines : 47,XYY (28%) ; 48,XYYY (68%); 49,XYYYY (4%). Since the most frequent cells bear three Y chromosomes and the karyotype of the propositu's father is normal, it is suggest that the propositus arose from an YYY sperm and that the observed mosaicism originated from a subsequent postzygotic non-disjunction.
摘要
对一名9岁男孩的染色体分析显示存在三种细胞系：47,XYY（28%）；48,XYYY（68%）；49,XYYYY（4%）。由于最常见的细胞带有三条Y染色体，且先证者父亲的核型正常，提示先证者源自一个YYY精子，观察到的嵌合体源自随后的合子后不分离。
