Summaries for Cone Dystrophy 4

UniProtKB/Swiss-Prot : 73 Achromatopsia 5: A form of achromatopsia, an ocular stationary disorder due to the absence of functioning cone photoreceptors in the retina. It is characterized by total colorblindness, low visual acuity, photophobia and nystagmus. ACHM5 inheritance is autosomal recessive.
Cone dystrophy 4: An early-onset cone dystrophy. Cone dystrophies are retinal dystrophies characterized by progressive degeneration of the cone photoreceptors with preservation of rod function, as indicated by electroretinogram. However, some rod involvement may be present in some cone dystrophies, particularly at late stage. Affected individuals suffer from photophobia, loss of visual acuity, color vision and central visual field. Another sign is the absence of macular lesions for many years. Cone dystrophies are distinguished from the cone-rod dystrophies in which some loss of peripheral vision also occurs.

MalaCards based summary : Cone Dystrophy 4, also known as achromatopsia 5, is related to retinal cone dystrophy 4 and aspergillosis, and has symptoms including photophobia An important gene associated with Cone Dystrophy 4 is PDE6C (Phosphodiesterase 6C). Affiliated tissues include retina, and related phenotypes are visual impairment and photophobia

OMIM : 56 Cone photoreceptor disorders form a clinical spectrum of diseases that include progressive cone dystrophy (COD) and complete and incomplete achromatopsia (ACHM). Impairment or death of cone photoreceptor cells is the clinical hallmark of these disorders. COD is a progressive cone disorder in which patients may initially have normal cone function but develop progressive visual acuity loss, increasing photophobia, color vision disturbances, and diminished cone responses on ERG, usually in the first or second decade of life. The visual acuity of these patients generally worsens to legal blindness before the fourth decade of life. ACHM is a stationary congenital autosomal recessive cone disorder characterized by low visual acuity, photophobia, nystagmus, and severe color vision defects. Patients with the complete ACHM subtype have no cone function on electroretinography, whereas those with incomplete ACHM show residual cone function (summary by Thiadens et al., 2009). (613093)
