RCV000213823 | SCV000272159 | uncertain significance | not specified | 2016-03-29 | criteria provided, single submitter | clinical testing | Variant classified as Uncertain Significance - Favor Benign. The p.Leu1151Val va riant in MYO7A has been reported in trans with a likely pathogenic variant in on e individual with hearing loss and one unaffected sibling. This variant has been identified in 1/24050 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Although this variant has been seen in t he general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analyses suggest that the p.Leu1151Val variant may impact the protein, though this information is not pre dictive enough to determine pathogenicity. While the clinical significance of th e p.Leu1151Val variant is uncertain, it is likely to be benign because it is lik ely in trans with a likely pathogenic variant in MYO7 in a reportedly unaffected individual. |

RCV002518178 | SCV002966960 | uncertain significance | not provided | 2023-08-19 | criteria provided, single submitter | 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 expected to disrupt MYO7A protein function. ClinVar contains an entry for this variant (Variation ID: 229011). This variant has not been reported in the literature in individuals affected with MYO7A-related conditions. This variant is present in population databases (rs782465732, gnomAD 0.002%). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1151 of the MYO7A protein (p.Leu1151Val). |
