由于45,X/46,XY嵌合型Turner综合征病人有15～20%的机会发生性腺母细胞瘤或无性细胞瘤,因此这类病需同Y染色体缺失的性腺发育不全可以区别开来。在具有一个Y的嵌合型Turner综合征病人中,有1/3存在Y的结构改变,还有3%的病人在性染色体的某些部位上存在一个未查明的标记染色 As 45, X / 46, XY chimeric Turner syndrome patients have 15 to 20% chance of gonadoblastoma or dysgerminoma, so these diseases need to be missing with the Y chromosome gonadal hypoplasia can be distinguished.
