摘要

老年性loken综合征(SLS)是一种罕见的常染色体隐性遗传病,其特征为肾病和早发性视网膜变性。我们使用一个患有SLS的伊朗大家庭来建立分子遗传学诊断。根据临床评估,我们对两个受影响的家庭成员进行了纯合定位,并对与纯合区域一致的已知SLS基因进行了突变分析。在NPHP5/IQCB1染色体3q21.1上一个已知SLS位点的纯合区域,我们发现了一个纯合的无义突变R332X。这是伊朗SLS亲属分子遗传学诊断的第一份报告。

Senior-Loken syndrome secondary to NPHP5/IQCB1 mutation in an Iranian family.

Senior-Loken syndrome (SLS) is a rare autosomal recessive disease characterized by nephronophthisis and early-onset retinal degeneration. We used a large Iranian family with SLS to establish a molecular genetic diagnosis. Following clinical evaluation, we undertook homozygosity mapping in two affected family members and mutational analysis in known SLS genes coinciding with regions of homozygosity. In a region of homozygosity coinciding with a known SLS locus on chromosome 3q21.1, we found a homozygous non-sense mutation R332X in NPHP5/IQCB1. This is the first report of a molecular genetic diagnosis in an Iranian kindred with SLS.
