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 | Jun 23, 2017 | The p.Val411Ala variant in MYO7A has been reported in 1 individual with autosoma l recessive hearing loss and 1 individual with unilateral hearing loss, however a second variant in MYO7A was not detected in either individual (Kothiyal 2010, LMM unpublished data, ClinVar Variation ID 43139). In addition, the variant was reported in 1 individual with autosomal dominant retinitis pigmentosa, however t his individual carried another variant that was more likely responsible for the disease (Sujirakul 2015). This variant has also been identified in 4/34106 Latin o chromosomes and 3/23546 African chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs369916141); however this fre quency is not high enough to rule out a pathogenic role. Computational predictio n tools and conservation analysis suggest that the variant may impact the protei n, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of the p.Val411Ala variant is uncertain. - |

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 18, 2024 | This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 411 of the MYO7A protein (p.Val411Ala). This variant is present in population databases (rs369916141, gnomAD 0.01%). This missense change has been observed in individual(s) with deafness and/or retinitis pigmentosa (PMID: 26164827, 33297549). ClinVar contains an entry for this variant (Variation ID: 43139). 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 expected to disrupt MYO7A protein function with a positive predictive value of 95%. 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. - |
