Retinitis pigmentosa 6(RP6)

MedGen UID:
333305
Concept ID:
C1839368
Disease or Syndrome
Synonyms: RETINITIS PIGMENTOSA, X-LINKED RECESSIVE, 6; RP 6
 
Monarch Initiative: MONDO:0000910
OMIM®: 312612

Definition

A retinitis pigmentosa that has material basis in variation in the chromosome region Xp21.3-p21.2. [from MONDO]

Clinical features

From HPO
Immotile cilia
MedGen UID:
383738
Concept ID:
C1855672
Finding
Recurrent respiratory infections
MedGen UID:
812812
Concept ID:
C3806482
Finding
An increased susceptibility to respiratory infections as manifested by a history of recurrent respiratory infections.
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.
Chorioretinal degeneration
MedGen UID:
99273
Concept ID:
C0521683
Pathologic Function
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.
