Cone-rod dystrophy 22(CORD22)

MedGen UID:
1794199
Concept ID:
C5561989
Disease or Syndrome
Synonyms: CONE-ROD DYSTROPHY 22; CORD22
 
Gene (location): TLCD3B (16p11.2)
 
Monarch Initiative: MONDO:0030440
OMIM®: 619531

Definition

Cone-rod dystrophy-22 (CORD22) is a retinal dystrophy characterized by loss of central vision due to cone photoreceptor degeneration, with onset of symptoms ranging from the first to fifth decades of life. There is significant degeneration of the macula, as well as generalized cone system involvement that predominates over rod system dysfunction, including in the peripheral retina (Bertrand et al., 2021). For a general phenotypic description and discussion of genetic heterogeneity of CORD, see CORD2 (120970). [from OMIM]

Clinical features

From HPO
Photophobia
MedGen UID:
43220
Concept ID:
C0085636
Sign or Symptom
Excessive sensitivity to light with the sensation of discomfort or pain in the eyes due to exposure to bright light.
Reduced visual acuity
MedGen UID:
65889
Concept ID:
C0234632
Finding
Diminished clarity of vision.
Absent foveal reflex
MedGen UID:
602333
Concept ID:
C0423420
Finding
Lack of the foveal reflex, which normally occurs as a result of the reflection of light from the ophthalmoscope in the foveal pit upon examination. The foveal reflex is a bright pinpoint of light that is observed to move sideways or up and down in response to movement of the opthalmoscope.
Bull eye maculopathy
MedGen UID:
321812
Concept ID:
C1828210
Finding
Progressive maculopathy characterized by concentric regions of hyper- and hypo-pigmentation.
Retinal pigment epithelial atrophy
MedGen UID:
333564
Concept ID:
C1840457
Finding
Atrophy (loss or wasting) of the retinal pigment epithelium observed on fundoscopy or fundus imaging.
Attenuation of retinal blood vessels
MedGen UID:
480605
Concept ID:
C3278975
Finding
Perifoveal ring of hyperautofluorescence
MedGen UID:
892724
Concept ID:
C4073099
Finding
Hyperautofluorescent macular lesion
MedGen UID:
893119
Concept ID:
C4073101
Finding
Increased amount of autofluorescence in the macula as ascertained by fundus autofluorescence imaging.
Undetectable pattern electroretinogram
MedGen UID:
900781
Concept ID:
C4280746
Finding
Absent response to a pattern electroretinogram (PERG).
Hypoautofluorescent retinal lesion
MedGen UID:
1369889
Concept ID:
C4476624
Finding
Decreased amount of autofluorescence in the retina as ascertained by fundus autofluorescence imaging.
