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]

Variant classified as Uncertain Significance - Favor Benign. The Gln1699Glu vari ant in MYO7A has not been reported in individuals with hearing loss. Computation al analyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhe n2, and SIFT) suggest that the Gln1699Glu variant may not impact the protein, th ough this information is not predictive enough to rule out pathogenicity. In sum mary, the clinical significance of this variant cannot be determined with certai nty; however, based upon the computational data, we lean towards a more likely b enign role. -

Review Status: criteria provided, single submitter
Collection Method: clinical testing

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt MYO7A protein function. ClinVar contains an entry for this variant (Variation ID: 178932). This variant has not been reported in the literature in individuals affected with MYO7A-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 1699 of the MYO7A protein (p.Gln1699Glu). -
