Abstract

Purpose: To describe ocular and extraocular abnormalities in two Ashkenazi Jewish families with infantile cataract and X-linked inheritance, and to identify their underlying mutations. Methods: Seven affected members were recruited. Medical history, clinical findings, and biometric measurements were recorded. Mutation analysis of the Nance–Horan syndrome (NHS) gene was performed by direct sequencing of polymerase chain reaction-amplified exons. Results: An unusual anterior Y-sutural cataract was documented in the affected male proband. Other clinical features among examined patients included microcorneas, long and narrow faces, and current or previous dental anomalies. A nonsense mutation was identified in each family, including a previously described 742 C>T, p.(Arg248*) mutation in Family A, and a novel mutation 2915 C>A, p.(Ser972*) in Family B. Conclusions: Our study expands the repertoire of NHS mutations and the related phenotype, including newly described anterior Y-sutural cataract and dental findings.
