Retinitis pigmentosa 38(RP38)

MedGen UID:
462578
Concept ID:
C3151228
Disease or Syndrome
Synonyms: ROD-CONE DYSTROPHY, CHILDHOOD-ONSET; RP38
 
Gene (location): MERTK (2q13)
 
Monarch Initiative: MONDO:0013469
OMIM®: 613862

Definition

Retinitis pigmentosa (RP) describes a group of disorders with progressive degeneration of rod and cone photoreceptors in a rod-cone pattern of dysfunction. RP has a prevalence of 1 in 3,500, and is genetically and phenotypically heterogeneous (summary by Mackay et al., 2010). For a general phenotypic description and a discussion of genetic heterogeneity of retinitis pigmentosa, see 268000. [from OMIM]

Clinical features

From HPO
Night blindness
MedGen UID:
10349
Concept ID:
C0028077
Disease or Syndrome
Inability to see well at night or in poor light.
Constriction of peripheral visual field
MedGen UID:
68613
Concept ID:
C0235095
Finding
An absolute or relative decrease in retinal sensitivity extending from edge (periphery) of the visual field in a concentric pattern. The visual field is the area that is perceived simultaneously by a fixating eye.
Macular atrophy
MedGen UID:
140841
Concept ID:
C0423421
Finding
Well-demarcated area(s) of partial or complete depigmentation in the macula, reflecting atrophy of the retinal pigment epithelium with associated retinal photoreceptor loss.
Optic disc pallor
MedGen UID:
108218
Concept ID:
C0554970
Finding
A pale yellow discoloration of the optic disc (the area of the optic nerve head in the retina). The optic disc normally has a pinkish hue with a central yellowish depression.
Progressive visual loss
MedGen UID:
326867
Concept ID:
C1839364
Finding
A reduction of previously attained ability to see.
Peripheral retinal atrophy
MedGen UID:
765930
Concept ID:
C3553016
Finding
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.
