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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Apr 28, 2015 | The p.Gly671Ser variant in MYO7A has previously been reported in one Chinese ind ividual with dominant hearing loss (Sun 2011). The variant segregated with disea se in one affected relative, but additional affected family members were not tes ted (Sun 2011). The p.Gly671Ser variant has not been identified in large populat ion studies. Computational prediction tools and conservation analyses do not pro vide strong support for or against an impact to the protein. In summary, the cli nical significance of the p.Gly671Ser variant is uncertain. - |
