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]

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMar 02, 2017The p.Arg444Met variant in DFNA5 has not been previously reported in individuals with hearing loss, but has been identified in 1/16486 of South Asian chromosome s by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbS NP rs780683974). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Splice predictio n tools suggest that this variant may result in the creation of a cryptic splice site, though this information is not predictive enough to determine pathogenici ty. Additional computational prediction tools and conservation analysis do not p rovide strong support for or against an impact to the protein. Pathogenic varian ts in DFNA5 reported to date result in skipping of exon 8; however, this variant is located in exon 10. In summary, the clinical significance of the p.Arg444Met variant is uncertain. -
