[Genetic heterogeneity of retinitis pigmentosa]

The authors present a classification of retinitis pigmentosa (rp) based on the modes of inheritance. Known genetic conditions of autosomal recessive, X-linked recessive and autosomal dominant forms of rp are shown, presenting molecular principles of the illness. They also describe clinical subtypes of rp with suggested genotype-phenotype correlations and principles of modern genetic diagnostics and genetic counselling.
