Retinitis pigmentosa 28(RP28)

MedGen UID:
244030
Concept ID:
C1419614
Disease or Syndrome
Synonyms: RP 28; RP28
 
Gene (location): FAM161A (2p15)
 
Monarch Initiative: MONDO:0011630
OMIM®: 606068

Definition

Any retinitis pigmentosa in which the cause of the disease is a mutation in the FAM161A gene. [from MONDO]

Clinical features

From HPO
Nyctalopia
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.
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.
Bone spicule pigmentation of the retina
MedGen UID:
323029
Concept ID:
C1836926
Finding
Pigment migration into the retina in a bone-spicule configuration (resembling the nucleated cells within the lacuna of bone).
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.
