Abstract

A 19-year old woman has been found whose red cells are a mixture of groups A1B (60%) and A1 (40%). Tests for many other genetic markers show no other evidence of mosaicism. She is not a twin and her parents and a sib are of normal ABO type. The cause of her dual population of red cells cannot be established, but may be an effect of somatic crossing over or mutation.

摘要

发现一名19岁女性，其红细胞为A1B型（60%）和A1型（40%）的混合。对许多其他遗传标记的检测未显示嵌合体的其他证据。她不是双胞胎，其父母和一个兄弟姐妹的ABO血型正常。其红细胞双重群体的原因无法确定，但可能是体细胞交换或突变的结果。
