New mutations in the NHS gene in Nance-Horan Syndrome families from the Netherlands.
Mutations in the NHS gene cause Nance-Horan Syndrome (NHS), a rare X-chromosomal recessive disorder with variable features, including congenital cataract, microphthalmia, a peculiar form of the ear and dental anomalies. We investigated the NHS gene in four additional families with NHS from the Netherlands, by dHPLC and direct sequencing. We identified an unique mutation in each family. Three out of these four mutations were not reported before. We report here the first splice site sequence alteration mutation and three protein truncating mutations. Our results suggest that X-linked cataract and NHS are allelic disorders.
