Abstract

A 48,XXYY Sardinian patient, born to a 46,XX mother heterozygous for the Gd Mediterranean mutant, and to a 46,XY father hemizygous for the same mutant, was found to have a mosaic distribution of G6PD(+) and G6PD(-) peripheral red blood cells. The most likely interpretation of this finding is that the propositus is an additional example of an XXYY zygote derived from a consecutive meiotic non-disjunction during paternal gametogenesis.

摘要

一名48,XXYY的撒丁岛患者,其母亲为46,XX,是Gd地中海突变体的杂合子,父亲为46,XY,是同一突变体的半合子。该患者外周血红细胞中G6PD(+)和G6PD(-)呈嵌合分布。这一发现最可能的解释是,该患者是父方配子发生过程中连续减数分裂不分离产生的XXYY合子的又一个例子。
