Abstract

Abstract: Purpose : To identiy the disease causing mutation in a Chinese family presenting with early-onset cataract and dental anomalies. Materials and Methods : A specific Hereditary Eye Disease Enrichment Panel (HEDEP) (personalized customization by MyGenostics, Baltimore, MD) based on targeted exome capture technology was used to collect the protein coding regions of 30 early-onset cataract associated genes, and high throughput sequencing was done with Illumina HiSeq 2000 platform. The identified variant was confirmed with Sanger sequencing. Results : A novel deletion in exon 4 (c.852delG) of NHS gene was identified; the identified 1 bp deletion altered the reading frame and was predicted to result in a premature stop codon after the addition of twelve novel amino acid (p.S285PfsX13). This mutation co-segregated in affected males and obligate female carriers, but was absent in 100 matched controls. Conclusions : Our findings broaden the spectrum of NHS mutations causing Nance-Horan syndrome and phenotypic spectrum of the disease in Chinese patients.
