Retinitis pigmentosa 43(RP43)

MedGen UID:
462489
•Concept ID:
C3151139
•
Disease or Syndrome
Synonym: RP43
 
Gene (location): PDE6A (5q32)
 
Monarch Initiative: MONDO:0013437
OMIM®: 613810

Definition

Retinitis pigmentosa-43 (RP43) is characterized by night blindness in the first decade of life, with progressive loss of peripheral visual fields and reduction in visual acuity. Examination reveals typical features of RP, including waxy pallor of optic disc, attenuated retinal vessels, and bone-spicule pigment in midperipheral retina. Macular edema and/or atrophy has been observed in some patients. Electroretinographic responses are markedly reduced or absent (summary by Huang et al., 1995 and Corton et al., 2010). [from OMIM]

Visual impairment
MedGen UID:
777085
•Concept ID:
C3665347
•
Finding
Visual impairment (or vision impairment) is vision loss (of a person) to such a degree as to qualify as an additional support need through a significant limitation of visual capability resulting from either disease, trauma, or congenital or degenerative conditions that cannot be corrected by conventional means, such as refractive correction, medication, or surgery.

Rod-cone dystrophy
MedGen UID:
1632921
•Concept ID:
C4551714
•
Disease or Syndrome
An inherited retinal disease subtype in which the rod photoreceptors appear to be more severely affected than the cone photoreceptors. Typical presentation is with nyctalopia (due to rod dysfunction) followed by loss of mid-peripheral field of vision, which gradually extends and leaves many patients with a small central island of vision due to the preservation of macular cones.

Pigmentary retinopathy
MedGen UID:
1643295
•Concept ID:
C4551715
•
Disease or Syndrome
An abnormality of the retina characterized by pigment deposition. It is typically associated with migration and proliferation of macrophages or retinal pigment epithelial cells into the retina; melanin from these cells causes the pigmentary changes. Pigmentary retinopathy is a common final pathway of many retinal conditions and is often associated with visual loss.
