Molecular genetics of retinitis pigmentosa

Abstract

Hereditary degenerations and dysfunctions of the retina are an extremely heterogeneous group of diseases. This summary deals with recent advances in the molecular genetics of a subset of those disorders, namely, those encompassed under the diagnosis 'retinitis pigmentosa'. Over 20 loci where mutations cause retinitis pigmentosa have been mapped; the review focuses on the seven retinitis pigmentosa loci that have been identified.
