Retinitis pigmentosa 39(RP39)

MedGen UID:
462488
•Concept ID:
C3151138
•
Disease or Syndrome
Synonym: RP39
 
Gene (location): USH2A (1q41)
 
Monarch Initiative: MONDO:0013436
OMIM®: 613809

Definition

Retinitis pigmentosa-39 (RP39) is characterized by the typical features of RP, including constriction of visual fields and reduced vision, with the fundus showing bone-spicule pigment deposition and attenuation of retinal vessels (Kaiserman et al., 2007; Jung et al., 2023). For a general phenotypic description and a discussion of genetic heterogeneity of retinitis pigmentosa (RP), see 268000. [from OMIM]

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.

Visual field defect
MedGen UID:
854603
•Concept ID:
C3887875
•
Finding
An absolute or relative reduction in the extent of the normal field of vision.
See: Feature record | Search on this feature
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.
