[[[Sanger]]]

Retinitis Pigmentosa (RP) is the most common form of hereditary retinal dystrophy characterised by photoreceptor degeneration. RP manifests with initial night blindness and tunnel vision, followed by secondary loss of cone photoreceptors, leading to reduced visual acuity and macular degeneration. The onset and progression of RP and the severity of symptoms can vary significantly between patients, even within the same family. Nearly 100 different autosomal dominant inherited forms of RP are known. In up to >80% of autosomal dominantly inherited RP, the genetic predisposition can be identified (depending on population and clinical preselection). There is sometimes incomplete penetrance and varying clinical expression. An inconspicuous genetic finding does not mean that the suspected clinical diagnosis is excluded. Autosomal recessively inherited RP is identified in more than half of all patients. Nearly 100 different autosomal recessive inherited forms of RP are currently known. In up to >80% of the recessively inherited RP forms (depending on the population and clinical preselection) the genetic predisposition can be identified. There are often different clinical manifestations. An inconspicuous genetic finding does not mean that the suspected clinical diagnosis is excluded.
