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 Arg1102Trp variant in MYH14 has not been reported in the literature nor prev iously identified by our laboratory. Computational analyses (biochemical amino a cid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide str ong support for or against an impact to the protein. Additional data is needed t o determine the clinical significance of this variant. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.3181C>T (p.R1061W) alteration is located in exon 25 (coding exon 24) of the MYH14 gene. This alteration results from a C to T substitution at nucleotide position 3181, causing the arginine (R) at amino acid position 1061 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
