Mutations in the CLCN5 gene, mapped in Xp11.22, have been recently reported to be associated with X-linked nephrolithiasis, X-linked recessive hypophosphataemic rickets and Dent's disease. We report a missense mutation in exon 6 of the CLCN5 gene. The mutation in this pedigree is S244L, the same mutation as has previously been described in an Italian family showing a similar pathology. However, in the family reported here, affected males have developed neither nephrolithiasis nor nephrocalcinosis. The question arises whether we are dealing with a milder phenotype or whether a more severe pathology will develop with ageing.
CLCN5基因定位于Xp11.22,最近有报道称该基因突变与X连锁肾结石、X连锁隐性低磷性佝偻病和丹特病有关。我们报告了CLCN5基因外显子6中的一个错义突变。这个家系中的突变是S244L,与之前在一个表现出类似病理特征的意大利家系中描述的突变相同。然而,在本文报道的这个家系中,患病男性既没有发生肾结石,也没有发生肾钙质沉着症。问题出现了,我们面对的是一种较轻的表型,还是随着年龄增长会出现更严重的病理状况。
