Genes affected
TMIE (HGNC:30800): (transmembrane inner ear) This gene encodes a transmembrane inner ear protein. Studies in mouse suggest that this gene is required for normal postnatal maturation of sensory hair cells in the cochlea, including correct development of stereocilia bundles. This gene is one of multiple genes responsible for recessive non-syndromic deafness (DFNB), also known as autosomal recessive nonsyndromic hearing loss (ARNSHL), the most common form of congenitally acquired inherited hearing impairment.

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.Thr73Met variant in TMIE has not been previously reported in individuals w ith hearing loss. It has been identified in 1/8618 East Asian and 1/66590 Europe an chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinsti tute.org); however, its frequency is not high enough to rule out a pathogenic ro le. Computational prediction tools and conservation analyses do not provide stro ng support for or against an impact to the protein. In summary, the clinical sig nificance of the p.Thr73Met variant is uncertain. -
