We report on a 16 month old girl with hypomelanosis of Ito and a balanced de novo (X;13)(q10;q10) translocation in which the der(Xp13q) had the X centromere (as assessed by FISH with the DXZ3 probe). A functional Xp disomy was shown in a small proportion of cultured lymphocytes by means of a BrdU terminal pulse. This observation supports the notion of a distinct form of hypomelanosis of Ito resulting from a functional Xp disomy.
我们报告了一名16个月大的患有伊藤色素减退症的女孩,其存在一种平衡的新生(X;13)(q10;q10)易位,其中衍生的(Xp13q)具有X染色体着丝粒(通过使用DXZ3探针的荧光原位杂交评估)。通过BrdU末端脉冲在一小部分培养的淋巴细胞中显示出功能性Xp双体。这一观察结果支持了伊藤色素减退症的一种独特形式是由功能性Xp双体导致的这一观点。
