Genes affected

MYH9 (HGNC:7579): (myosin heavy chain 9) This gene encodes a conventional non-muscle myosin; this protein should not be confused with the unconventional myosin-9a or 9b (MYO9A or MYO9B). The encoded protein is a myosin IIA heavy chain that contains an IQ domain and a myosin head-like domain which is involved in several important functions, including cytokinesis, cell motility and maintenance of cell shape. Defects in this gene have been associated with non-syndromic sensorineural deafness autosomal dominant type 17, Epstein syndrome, Alport syndrome with macrothrombocytopenia, Sebastian syndrome, Fechtner syndrome and macrothrombocytopenia with progressive sensorineural deafness.

The Tyr278Cys variant in MYH9 has not been previously reported in individuals wi th hearing loss or in large population studies. Computational analyses (biochemi cal amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the Tyr278Cys variant may impact the protein, though this information is n ot predictive enough to determine pathogenicity. Additional information is neede d to fully assess the clinical significance of this variant. -
