Retinitis pigmentosa 73(RP73)

MedGen UID:
907690
Concept ID:
C4225287
Disease or Syndrome
Synonym: RP73
 
Gene (location): HGSNAT (8p11.21-11.1)
 
Monarch Initiative: MONDO:0014687
OMIM®: 616544

Definition

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

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.
Photopsia
MedGen UID:
43219
Concept ID:
C0085635
Disease or Syndrome
Perceived flashes of light.
Central scotoma
MedGen UID:
57750
Concept ID:
C0152191
Finding
An area of depressed vision located at the point of fixation and that interferes with central vision.
Color vision defect
MedGen UID:
115964
Concept ID:
C0234629
Finding
An anomaly in the ability to discriminate between or recognize colors.
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.
Preretinal fibrosis
MedGen UID:
87388
Concept ID:
C0339543
Anatomical Abnormality
An epiretinal membrane is a thin sheet of fibrous tissue that can develop on the surface of the macular area of the retina and cause a disturbance in vision. An epiretinal membrane area can develop on the thin macular area of the retin. An epiretinal membrane is also sometimes called a macular pucker, premacular fibrosis, surface wrinkling retinopathy or cellophane maculopathy.
Blurred vision
MedGen UID:
91020
Concept ID:
C0344232
Finding
Lack of sharpness of vision resulting in the inability to see fine detail.
Ring scotoma
MedGen UID:
140951
Concept ID:
C0438434
Finding
An annular field defect centered on fixation.
Retinal atrophy
MedGen UID:
101075
Concept ID:
C0521694
Disease or Syndrome
Well-demarcated area(s) of partial or complete depigmentation in the fundus, reflecting atrophy of the retinal pigment epithelium with associated retinal photoreceptor loss.
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.
Geographic atrophy
MedGen UID:
323488
Concept ID:
C1536085
Disease or Syndrome
Sharply demarcated area of partial or complete depigmentation of the fundus reflecting atrophy of the retinal pigment epithelium with associated retinal photoreceptor loss. The margins of the de-pigmented area are usually scalloped and the large choroidal vessels are visible through the atrophic retinal pigment epithelium.
Peripapillary atrophy
MedGen UID:
473480
Concept ID:
C1719838
Pathologic Function
Thinning in the layers of the retina and retinal pigment epithelium around the optic nerve.
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).
Visual field defect
MedGen UID:
854603
Concept ID:
C3887875
Finding
An absolute or relative reduction in the extent of the normal field of vision.
Macular crystals
MedGen UID:
892788
Concept ID:
C4072988
Finding
Crystalline deposits in the macula.
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.
