Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
141025
Concept ID:
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).

Definition

A very rare disorder associating pseudopapilloedema (optic disc swelling not secondary to increased intracranial pressure) mixed hearing loss, facial dysmorphism and limb extremity anomalies. Only 4 cases have been reported in the literature from 3 inbred sibships. The affected patients have no intellectual deficit. Transmitted as an autosomal recessive trait. [from SNOMEDCT_US]

Atresia of the external auditory canal
MedGen UID:
78613
Concept ID:
C0266597

154361
Concept ID:
C0575158
