RCV000036141 | SCV000059793 | likely benign | not specified | 2011-02-17 | criteria provided, single submitter | clinical testing | Val1454Ile in exon 33 of MYO7A: This variant is not expected to have clinical si gnificance because computational analyses (PolyPhen2, SIFT, AlignGVGD) do not su ggest a high likelihood of impact to the protein. Of note, fruitfly has an isole ucine at this position despite high nearby amino acid conservation. |

RCV001244369 | SCV001417583 | uncertain significance | not provided | 2022-09-12 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 1454 of the MYO7A protein (p.Val1454Ile). This variant is present in population databases (rs397516309, gnomAD 0.04%). This missense change has been observed in individual(s) with Usher syndrome (PMID: 26338283). ClinVar contains an entry for this variant (Variation ID: 43237). 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. 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. |
