Illumina Laboratory Services, Illumina RCV000293544 SCV000401177 uncertain significance Autosomal recessive nonsyndromic hearing loss 3 2018-01-12 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000610556 SCV000731791 uncertain significance not specified 2017-07-20 criteria provided, single submitter clinical testing The p.Gln2479Arg variant in MYO15A has not been previously reported in individua ls with hearing loss, but has been reported in ClinVar (Variation ID# 322160) as of uncertain significant. This variant has been identified in 5/15380 East Asi an chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadin stitute.org; dbSNP rs756565842). Computational prediction tools and conservatio n analyses do not provide strong support for or against an impact to the protein . In summary, the clinical significance of the p.Gln2479Arg variant is uncertain .
Labcorp Genetics (formerly Invitae), Labcorp RCV002522919 SCV002998659 uncertain significance not provided 2022-01-27 criteria provided, single submitter clinical testing This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 2479 of the MYO15A protein (p.Gln2479Arg). This variant is present in population databases (rs756565842, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with MYO15A-related conditions. ClinVar contains an entry for this variant (Variation ID: 322160). 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 MYO15A 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.
