Summaries for Bietti Crystalline Corneoretinal Dystrophy

OMIM : 56 Bietti crystalline corneoretinal dystrophy is an autosomal recessive retinal dystrophy characterized by numerous tiny glistening yellow-white crystals at the posterior pole of the retina, associated with atrophy of the retinal pigment epithelium (RPE), pigment clumps, and choroidal sclerosis. Most cases have similar crystals at the corneoscleral limbus. The disorder is progressive; most patients develop decreased vision, nyctalopia, and paracentral scotomata between the second and fourth decades of life. Patients later develop peripheral visual field loss and marked visual impairment, usually progressing to legal blindness by the fifth or sixth decade of life. In a series of European patients diagnosed with nonsyndromic retinitis pigmentosa (RP; see 268000), BCD accounted for approximately 3% of all nonsyndromic RP and 10% of nonsyndromic autosomal recessive RP. Histopathology shows advanced panchorioretinal atrophy, with crystals and complex lipid inclusions seen in choroidal fibroblasts, corneal keratocytes, and conjunctival and skin fibroblasts, as well as in circulating lymphocytes, suggesting that BCD may result from a systemic abnormality of lipid metabolism (summary by Li et al., 2004). (210370)

MalaCards based summary : Bietti Crystalline Corneoretinal Dystrophy, also known as bietti crystalline dystrophy, is related to choroidal dystrophy, central areolar, 1 and scotoma. An important gene associated with Bietti Crystalline Corneoretinal Dystrophy is CYP4V2 (Cytochrome P450 Family 4 Subfamily V Member 2). The drugs Pyridoxine and Ornithine have been mentioned in the context of this disorder. Affiliated tissues include retina, eye and skin, and related phenotypes are high myopia and retinal degeneration

Disease Ontology : 12 A retinal degeneration that is characterized by crystals in the cornea, shiny deposits on the retina and progressive atrophy of the retina, choriocapillaris and choroid, has material basis in autosomal recessive inheritance of homozygous or compound heterozygous mutation in the CYP4V2 gene on chromosome 4q35.

Genetics Home Reference : 25 Bietti crystalline dystrophy is a disorder in which numerous small, yellow or white crystal-like deposits of fatty (lipid) compounds accumulate in the light-sensitive tissue that lines the back of the eye (the retina). The deposits damage the retina, resulting in progressive vision loss. People with Bietti crystalline dystrophy typically begin noticing vision problems in their teens or twenties. They experience a loss of sharp vision (reduction in visual acuity) and difficulty seeing in dim light (night blindness). They usually lose areas of vision (visual field loss), most often side (peripheral) vision. Color vision may also be impaired. The vision problems may worsen at different rates in each eye, and the severity and progression of symptoms varies widely among affected individuals, even within the same family. However, most people with this condition become legally blind by their forties or fifties. Most affected individuals retain some degree of vision, usually in the center of the visual field, although it is typically blurry and cannot be corrected by glasses or contact lenses. Vision impairment that cannot be improved with corrective lenses is called low vision.

NIH Rare Diseases : 52 Bietti crystalline corneoretinal dystrophy is an inherited eye disease . Symptoms include crystals in the cornea (the clear covering of the eye); yellow, shiny deposits on the retina; and progressive atrophy of the retina, choriocapillaries and choroid (the back layers of the eye). This tends to lead to progressive night blindness and loss of visual acuity. Bietti crystalline corneoretinal dystrophy is caused by mutations in the CYP4V2 gene and inherited in an autosomal recessive fashion.

KEGG : 36 Bietti crystalline corneoretinal dystrophy (BCD) is an autosomal recessive retinal dystrophy characterized by crystalline deposits in the retina, followed by progressive atrophy of the retinal pigment epithelium (RPE), choriocapillaris, and photoreceptors. BCD usually occurs in the second or third decade of life. CYP4V2 has been identified as the causative gene for BCD.

UniProtKB/Swiss-Prot : 73 Bietti crystalline corneoretinal dystrophy: An autosomal recessive ocular disease characterized by retinal degeneration and marginal corneal dystrophy. Typical features include multiple glistening intraretinal crystals scattered over the fundus, a characteristic degeneration of the retina, and sclerosis of the choroidal vessels, ultimately resulting in progressive night blindness and constriction of the visual field. Most patients have similar crystals at the corneoscleral limbus. Patients develop decreased vision, nyctalopia, and paracentral scotomata between the 2nd and 4th decade of life. Later, they develop peripheral visual field loss and marked visual impairment, usually progressing to legal blindness by the 5th or 6th decade of life.
