Kidney int:早发性肾结石的测序研究!

2017-09-14 MedSci MedSci原创

近年来,肾结石的发病率继续上升。此前有研究显示,使用已知可以导致肾结石病的30个基因的基因组测序,可以在11.4%的成人发病的肾结石或肾钙质沉着的个体中以及在16.7-20.8%的18岁以前发病的个体中检测到单因素原因。为了克服测序的局限性,近期,一项发表在杂志Kidney int上的研究在51个家庭中使用了整个外显子测序,这些受试者在25岁以前至少出现一个肾结石或肾脏超声检查发现了肾钙质沉着症,

近年来,肾结石的发病率继续上升。此前有研究显示,使用已知可以导致肾结石病的30个基因的基因组测序,可以在11.4%的成人发病的肾结石或肾钙质沉着的个体中以及在16.7-20.8%的18岁以前发病的个体中检测到单因素原因。


为了克服测序的局限性,近期,一项发表在杂志Kidney int上的研究在51个家庭中使用了整个外显子测序,这些受试者在25岁以前至少出现一个肾结石或肾脏超声检查发现了肾钙质沉着症,此项研究旨在确定潜在的分子遗传病因。

最终,研究者们在51个家庭中的15个,通过整个外显子测序检测到单因因果突变。检测到七个隐性基因(AGXT,ATP6V1B1,CLDN16,CLDN19,GRHPR,SLC3A1,SLC12A1)、一个显性基因(SLC9A3R1)和一个具有隐性和显性遗传的基因(SLC34A1)中出现突变。其中,19种不同突变中的7种以前没有被描述为可致病的。

在一个家庭中,检测到代表引起肾结石的基因的117种基因中有一个可能是致病突变。

在15个家庭中的9个家庭中,遗传诊断可能对结石的管理预防具有特定的影响。与此项队列中较高检出率相关的几个因素为:年龄较小时发作肾结石病/肾钙质沉着症,家族中多个成员受影响,存在血缘关系。

此项研究建立了整个外显子序列在25岁以前表现为肾结石/肾钙质沉着症的个体中作为分子遗传中的诊断方法。
