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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The Arg120His varia nt in MYO7A has not been reported in the literature nor previously identified by our laboratory. This residue is conserved in mammals though not in lower specie s. Computational analyses (PolyPhen, SIFT, AlignGVGD) provide inconsistent predi ctions regarding the impact to the protein though this information is not very p redictive of pathogenicity anyway. In summary, the clinical significance of this variant cannot be determined at this time. -
