Retinitis pigmentosa 90(RP90)

MedGen UID:
1733837
•Concept ID:
C5436588
•
Disease or Syndrome
Synonyms: RETINITIS PIGMENTOSA 90; RP90
 
Gene (location): IDH3A (15q25.1)
 
Monarch Initiative: MONDO:0033563
OMIM®: 619007

Definition

Retinitis pigmentosa-90 (RP90) is characterized by early-onset night blindness, within the first decade of life. Patients exhibit other typical features of RP, including retinal vessel attenuation, optic disc pallor, and retinal pigment epithelium (RPE) atrophy and pigmentation abnormalities. Macular pseudocoloboma and cystoid macular edema have also been observed (Pierrache et al., 2017). For a discussion of genetic heterogeneity of RP, see 268000. [from OMIM]

Clinical features

From HPO
Cystoid macular edema
MedGen UID:
7435
•Concept ID:
C0024440
•
Disease or Syndrome
Dominant cystoid macular dystrophy (DCMD) is a progressive retinal dystrophy characterized primarily by early-onset cystoid fluid collections in the neuroretina (summary by Saksens et al., 2015).

Strabismus
MedGen UID:
21337
•Concept ID:
C0038379
•
Disease or Syndrome
A misalignment of the eyes so that the visual axes deviate from bifoveal fixation. The classification of strabismus may be based on a number of features including the relative position of the eyes, whether the deviation is latent or manifest, intermittent or constant, concomitant or otherwise and according to the age of onset and the relevance of any associated refractive error.

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.

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).

MedGen UID:
333564
•Concept ID:
C1840457
•
Finding
