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]

Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Nov 06, 2013	Variant classified as Uncertain Significance - Favor Benign. The Asp576Asn varia nt in MYO7A has not been previously reported in individuals with hearing loss, b ut has been identified in 0.1% (4/4022) of African American chromosomes by the N HLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs187165 412). Although this variant has been seen in the general population, its frequen cy is not high enough to rule out a pathogenic role. Computational analyses (bi ochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) d o not provide strong support for or against an impact to the protein. In summary , additional information is needed to determine the clinical significance of th is variant.. -
