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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineFeb 07, 2013Variant classified as Uncertain Significance - Favor Benign. The Gly14Ser varian t in TMIE has not been reported in the literature nor previously identified by o ur laboratory. Computational analyses (biochemical amino acid properties, conser vation, AlignGVGD, PolyPhen2, and SIFT) suggest that the Gly14Ser variant may no t impact the protein, though this information is not predictive enough to rule o ut pathogenicity. In summary, the clinical significance of this variant cannot b e determined with certainty; however based upon the weak predicted impact and ab sence of any data supporting pathogenicity, we would lean towards a more likely benign role. -
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2022The c.40G>A (p.G14S) alteration is located in exon 1 (coding exon 1) of the TMIE gene. This alteration results from a G to A substitution at nucleotide position 40, causing the glycine (G) at amino acid position 14 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
