MedGen UID:
316921
•Concept ID:
C1832162
•
Disease or Syndrome
Synonyms: HJMD; HYPOTRICHOSIS WITH CONE-ROD DYSTROPHY; Juvenile macular degeneration and hypotrichosis; Juvenile macular dystrophy and congenital hypotrichosis
Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:

C0441748
•
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
Autosomal recessive inheritance (Orphanet)
 
Gene (location): CDH3 (16q22.1)
 
Monarch Initiative: MONDO:0011107
OMIM®: 601553

Definition

Hypotrichosis with juvenile macular degeneration (HJMD) is a very rare syndrome characterized by sparse and short hair from birth followed by progressive macular degeneration leading to blindness. [from ORDO]

Blindness
MedGen UID:
99138
•Concept ID:
C0456909
•
Disease or Syndrome
Blindness is the condition of lacking visual perception defined as a profound reduction in visual perception. On the 6m visual acuity scale, blindness is defined as less than 3/60. On the 20ft visual acuity scale, blindness is defined as less than 20/400. On the decimal visual acuity scale, blindness is defined as less than 0.05. Blindness is typically characterized by a visual field of no greater than 10 degrees in radius around central fixation.
