Enhanced S Cone syndrome ESCS (15q23), Synonym/Favre Hyaloidoretinal degeneration, Synonym/Goldman-Favre syndrome variant

gene locus 15q23; includes Goldman-Favre syndrome; Hereditary autosomal recessive disorder; ENHANCED S-CONE SYNDROME; ESCS Clinical Synopsis;Eyes : Liquefied vitreous body; Preretinal band-shaped structures (veil); Macular edema ;Retinoschisis; Retinal pigmentary degeneration; Hemeralopia; Hyaloideoretinal degeneration; Vitreoretinal degeneration; Cataract; Night blindness; Lab:;Extinguished electroretinogram; Alternative titles; symbols; GOLDMANN-FAVRE SYNDROME, INCLUDED RETINOSCHISIS WITH EARLY HEMERALOPIA, INCLUDED; FAVRE HYALOIDEORETINAL DEGENERATION, INCLUDED; Gene map locus 15q23; mutations in the nuclear receptor gene NR2E3; Hereditary human retinal degenerative diseases usually affect the mature photoreceptor topography by reducing the number of cells through apoptosis, resulting in loss of visual function; Only one inherited retinal disease, the enhanced S-cone syndrome (ESCS), manifests a gain in function of photoreceptors; ESCS is an autosomal recessive retinopathy in which patients have increased sensitivity to blue light; perception of blue light is mediated by what is normally the least populous cone photoreceptor subtype, the S (short wavelength, blue) cones; People with ESCS also suffer visual loss, with night blindness occurring from early in life, varying degrees of L (long, red)- and M (middle, green)-cone vision, and retinal degeneration; The pattern of retinal dysfunction is a constant among ESCS patients, but the degree of clinically evident retinal degeneration can vary from minimal to severe; The latter condition is known as Goldmann-Favre syndrome----[OMIM Nov 2004]------
