Identification of three novel NHS mutations in families with Nance-Horan syndrome.

Year: 2007

Type: article

Abstract: PURPOSE: Nance-Horan Syndrome (NHS) is an infrequent and often overlooked X-linked disorder characterized by dense congenital cataracts, microphthalmia, and dental abnormalities. The syndrome is caused by mutations in the NHS gene, whose function is not known. The purpose of this study was to identify the frequency and distribution of NHS gene mutations and compare genotype with Nance-Horan phenotype in five North American NHS families. METHODS: Genomic DNA was isolated from white blood cells from NHS patients and family members. The NHS gene coding region and its splice site donor and acceptor regions were amplified from genomic DNA by PCR, and the amplicons were sequenced directly. RESULTS: We identified three unique NHS coding region mutations in these NHS families. CONCLUSIONS: This report extends the number of unique identified NHS mutations to 14.
