Background: Complete Congenital Stationary Night Blindness (CSNB) type 1A is an X-linked condition associated with reduced scotopic vision, myopia, nystagmus and mutations in the NYX (nyctalopin) gene. This paper reports a novel mutation identified in this gene associated with X-linked CSNB in a New Zealand Caucasian family. Methods: A 16 year old male, presenting with night blindness, underwent detailed phenotypic assessment including pedigree construction and electrophysiology testing. Genetic analysis was performed in the Division of Medical Molecular Genetics, University of Zurich, Switzerland. Other family members also underwent clinical examination and genetic testing. Results: Electrodiagnostic testing has confirmed the diagnosis of Type 1 (complete) CSNB in the proband and his maternal grandfather by ide.. View More»
