Retinitis pigmentosa 92(RP92)

MedGen UID:
1794232
•Concept ID:
C5562022
•
Disease or Syndrome
Synonyms: RETINITIS PIGMENTOSA 92; RP92
 
Gene (location): HKDC1 (10q22.1)
 
Monarch Initiative: MONDO:0030619
OMIM®: 619614

Definition

Retinitis pigmentosa-92 (RP92) is characterized by relatively mild disease, with onset of night blindness and vision loss in the third to sixth decades of life. Patients show abnormal pigmentation of the retina and have reduced scotopic responses on electroretinography (Zhang et al., 2018). For a general phenotypic description and discussion of genetic heterogeneity of RP, 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.

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.

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.
