Genes affected

GSDME (HGNC:2810): (gasdermin E) Hearing impairment is a heterogeneous condition with over 40 loci described. The protein encoded by this gene is expressed in fetal cochlea, however, its function is not known. Nonsyndromic hearing impairment is associated with a mutation in this gene. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Variant classified as Uncertain Significance - Favor Benign. The Gly373Asp varia nt in DFNA5 has not been previously reported in individuals with hearing loss, b ut has been identified in 0.07% (3/4406) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/;dbSNP rs146399 987). The glycine (Gly) at position 373 is not well conserved across species and the change to an aspartate (Asp) has been identified in dogs, suggesting that t his variant might be tolerated. Other computational prediction tools suggest tha t the Gly373Asp variant may not impact the protein, though this information is n ot predictive enough to rule out pathogenicity. In summary, the clinical signifi cance of this variant cannot be determined with certainty; however based upon th e arguments described above, we would lean towards a more likely benign role.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1118G>A (p.G373D) alteration is located in exon 8 (coding exon 7) of the DFNA5 gene. This alteration results from a G to A substitution at nucleotide position 1118, causing the glycine (G) at amino acid position 373 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
