MedGen UID:
Concept ID:
Disease or Syndrome
Synonyms: DEAFNESS, AUTOSOMAL RECESSIVE 18A; DFNB18 Nonsyndromic Hearing Loss and Deafness; DFNB18A
Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
Concept ID:
Intellectual Product
Autosomal recessive inheritance refers to genetic conditions that occur only when mutations are present in both copies of a given gene (i.e., the person is homozygous for a mutation, or carries two different mutations of the same gene, a state referred to as compound heterozygosity).
Gene: USH1C
Cytogenetic location: 11p15.1
OMIM: 602092

Disease characteristics

Excerpted from the GeneReview: Deafness and Hereditary Hearing Loss Overview
Hereditary hearing loss and deafness may be conductive, sensorineural, or a combination of both; syndromic (associated with malformations of the external ear or other organs or with medical problems involving other organ systems) or nonsyndromic (no associated visible abnormalities of the external ear or any related medical problems); and prelingual (before language develops) or postlingual (after language develops). [from GeneReviews]

Clinical features

Sensorineural hearing impairment
