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.

The p.Arg1790His variant in MYH14 has not been previously reported in individual s with hearing loss, but has been identified in 1/66722 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Computa tional prediction tools and conservation analysis suggest that this variant may impact the protein, though this information is not predictive enough to determin e pathogenicity. In summary, the clinical significance of the p.Arg1790His varia nt is uncertain. -

The c.5246G>A (p.R1749H) alteration is located in exon 37 (coding exon 36) of the MYH14 gene. This alteration results from a G to A substitution at nucleotide position 5246, causing the arginine (R) at amino acid position 1749 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
