Novel mutations in CACNA1F and NYX in Dutch families with X-linked congenital stationary night blindness

PURPOSE: To describe the clinical features and genetic analysis of eight X-linked congenital stationary night blindness (XLCSNB) Dutch patients. METHODS: Electroretinogram (ERG) measurements were assessed in Dutch patients. Molecular genetic testing by denaturing high performance liquid chromatography (DHPLC), single stranded conformation polymorphism (SSCP) analysis, and direct sequencing of the CACNA1F and NYX genes were performed in the patients possessing a negative Schubert Bornschein ERG. RESULTS: Molecular genetic testing of CACNA1F and NYX revealed three novel and two known CACNA1F seq... Mehr ...
