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 p.Glu380Lys variant in MYO7A has been reported in one Caucasian individual w ith Usher syndrome who carried a second variant of uncertain significance in MYO 7A (Le Quesne Stabej 2012). Data from large population studies are insufficient to assess the frequency of this variant. Computational prediction tools and cons ervation analyses suggest that the p.Glu380Lys variant may impact the protein, t hough this information is not predictive enough to determine pathogenicity. In s ummary, the clinical significance of the p.Glu380Lys variant is uncertain. -
