IllnessCone-rod dystrophy / macular dystrophy, retinitis pigmentosa; differential diagnosis [exp. panel]

NGS +

Inherited retinal dystrophies (RDs) are a group of diseases that can be syndromic or non-syndromic. The visual impairment can range from poor peripheral or night vision to complete blindness, the severity usually increasing with age. RDs can be divided into groups according to the affected photoreceptors and the manifestations or degree of atrophy within the retina. RD groups include rod-dominated diseases, cone-dominated diseases and generalized retinal degenerations involving both rod and cone photoreceptors. Among rod and cone dystrophies, progressive degenerative forms including retinitis pigmentosa can be distinguished as well as stationary forms known as congenital stationary night blindness. RDs thus occur due to abnormalities in the cellular structures of the retina as well as defects in the phototransduction cascade and visual cycle biochemistry. RD occurs during the entire life span from birth until after the age of 60. All classical transmission patterns are observed as well as rarely digenic heredity. Sometimes there is incomplete penetrance and often different clinical expression. An inconspicuous genetic finding does not mean a reliable exclusion of the suspected clinical diagnosis, since the molecular genetic diagnostic yield is incomplete (>50-65%).
