PNAS:WT1突变使得XX染色体个体发育出男性性器官

哺乳动物的性别决定是由两条遗传途径的拮抗性相互作用所决定的,这两条途径的不平衡可能会导致人类的性别发育障碍/差异(DSD)。

哺乳动物的性别决定是由两条遗传途径的拮抗性相互作用所决定的,这两条途径的不平衡可能会导致人类的性别发育障碍/差异(DSD)。

在46,XX基因型的带有睾丸DSD(TDSD)或卵睾DSD(OTDSD)的个体中,睾丸组织存在于性腺中。虽然许多病例中存在睾丸决定性基因SRY,但大多数SRY阴性患者的病因不明。

最近,研究人员对78名遗传病因不明的46,XX TDSD/OTDSD个体进行了外显子组测序,发现7名受试者(8.97%)具有影响Wilms'tumor 1(WT1)第四锌指(ZF4)的杂合变异(p.Ser478Thrfs*17,p.Pro481Leufs*15,p.Lys491Glu,p.Arg495Gln[x3],p.Arg495Gly)。

这些变异体在6个家族中是新生的(P=4.4×10-6),与对照人群相比,46,XX DSD中WT1变异体的发生率是富集的(P<1.8×10-4)。

将ZF4突变体引入人颗粒细胞系,导致内源性睾丸营养细胞转录上调,Wt1Arg495Gly/Arg495Gly XX小鼠显示胎儿性腺男性化。该表型可以通过突变蛋白与一个关键的促卵因子β-CATENIN的物理相互作用和封存的能力来解释,这可能导致睾丸特异性途径的上调。

因此,这些数据显示,与以往WT1和46,XY DSD的关联不同,WT1的ZF4变异是46,XX TDSD/OTDSD比较常见的原因。这扩大了与WT1变异相关的表型谱,并表明ZF4突变的WT1蛋白可以作为XX染色体背景下的protestis因子发挥作用。
