Retinitis pigmentosa 69(RP69)

MedGen UID:
862749
Concept ID:
C4014312
Disease or Syndrome
Synonym: RP69
 
Gene (location): KIZ (20p11.23)
 
Monarch Initiative: MONDO:0014345
OMIM®: 615780

Definition

Retinitis pigmentosa (RP), also designated rod-cone dystrophy, is characterized by initial night blindness due to rod dysfunction, with subsequent progressive constriction of visual fields, abnormal color vision, and eventual loss of central vision due to cone photoreceptor involvement (summary by El Shamieh et al., 2014). For 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.
Reduced visual acuity
MedGen UID:
65889
Concept ID:
C0234632
Finding
Diminished clarity of vision.
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.
Undetectable electroretinogram
MedGen UID:
383742
Concept ID:
C1855685
Finding
Lack of any response to stimulation upon electroretinography.
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.
Perifoveal hypoautofluorescence
MedGen UID:
1814406
Concept ID:
C5676842
Finding
Decreased amount of autofluorescence (emission of fluorescent light from ocular structures in the absence of sodium fluorescein) in the retina in the region surrounding the fovea.
