Genes affected

MYO7A (HGNC:7606): (myosin VIIA) This gene is a member of the myosin gene family. Myosins are mechanochemical proteins characterized by the presence of a motor domain, an actin-binding domain, a neck domain that interacts with other proteins, and a tail domain that serves as an anchor. This gene encodes an unconventional myosin with a very short tail. Defects in this gene are associated with the mouse shaker-1 phenotype and the human Usher syndrome 1B which are characterized by deafness, reduced vestibular function, and (in human) retinal degeneration. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

The Leu375Val variant in MYO7A has not been previously reported in individuals w ith hearing loss. Sequencing data from large population studies is insufficient to assess variant frequency. Computational analyses (biochemical amino acid prop erties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide strong supp ort for or against an impact to the protein. In summary, additional information is needed to determine the clinical significance of this variant. -
