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 Ser1757Ser variant in MYH14 has not been reported in the literature nor prev iously identified by our laboratory. The G to A substitution causes a sequence c hange 15 bases into the exon that could create an alternate 3?splice site leadin g to an out of frame deletion. Experimental evidence would be needed to evaluate this possibility. In summary, the clinical significance of these variants canno t be determined with certainty. -
