Purpose: To characterize the genetic defects associated with fundus albipunctatus (FAP) in patients in Israel. Methods: Twenty patients with FAP from diverse ethnicities underwent ophthalmic and electroretinogram tests following the International Society for Clinical Electrophysiology of Vision protocol. Genomic DNA was extracted from peripheral blood. Mutation analysis of the 11-cis retinol dehydrogenase (RDH5) gene was performed with direct sequencing of PCRamplified exons. Results: Four novel RDH5 gene mutations were identified. Of them, the null mutations c.343C>T (p.R54X) and c. 242delTGCC were most prevalent. Macular involvement was present in two patients who carry different mutation types. Conclusions: Mutation analysis of the RDH5 gene in the present series revealed four novel mutations and a previously reported one. No significant genotype-phenotype correlation was found.
