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.

Collection Method:clinical testing

The Gln1496Glu variant in MYH14 has not been previously reported in individuals with hearing loss, but it has been identified in 0.52% (1/192) of Luhya (Kenya) chromosomes by the 1000 Genomes Project (dbSNP rs141995460). Although this varia nt has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation anal yses suggest that the Gln1496Glu variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the Gln1496Glu variant is uncertain. -

Collection Method:clinical testing

The c.4363C>G (p.Q1455E) alteration is located in exon 31 (coding exon 30) of the MYH14 gene. This alteration results from a C to G substitution at nucleotide position 4363, causing the glutamine (Q) at amino acid position 1455 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
