Genes affected

MYH14 (HGNC:23212): (myosin heavy chain 14) This gene encodes a member of the myosin superfamily. The protein represents a conventional non-muscle myosin; it should not be confused with the unconventional myosin-14 (MYO14). Myosins are actin-dependent motor proteins with diverse functions including regulation of cytokinesis, cell motility, and cell polarity. Mutations in this gene result in one form of autosomal dominant hearing impairment. Multiple transcript variants encoding different isoforms have been found for this gene.

p.Gly384Cys in exon 11 of MYH14: This variant is not expected to have clinical s ignificance, because it has been identified in 1.3% (136/10142) of Ashkenazi Jew ish chromosomes including 1 homozygote by the Genome Aggregation Database (gnomA D, http://gnomad.broadinstitute.org/; dbSNP rs119103280). Although this variant has been reported as a de novo variant in one individual with moderate sensorine ural hearing loss (Donaudy 2004), the evidence is not sufficient to establish ca usality. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
