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.

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-46705816-GCCGC-G is Pathogenic according to our data. Variant chr3-46705816-GCCGC-G is described in ClinVar as [Pathogenic]. Clinvar id is 3389.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr3-46705816-GCCGC-G is described in Lovd as [Pathogenic].
