cone-rod dystrophy

A form of retinitis pigmentosa in which central visual loss occurs first. Common symptoms include progressive visual loss followed by the loss of color perception, and eventually peripheral visual loss and night blindness. The visual loss is not correctable with standard lenses. See: retinitis pigmentosa

Specifically, Sanger sequencing of ABCA4, PRPH2/RDS-peripherin, and ELOVL4 was negative except for Proband 1, who had a heterozygous ABCA4 missense variant (c.2588G>C; p.Gly863Ala) and no family history of Stargardt disease or cone-rod dystrophy. This substitution has been previously reported as disease-causing (rs76157638; HGMD ID CS024003), but not associated with pericentral retinal degeneration (PRD) [29-32].
