This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 1219 of the MYH14 protein (p.Gly1219Ser). This variant is present in population databases (rs200272339, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with MYH14-related conditions. ClinVar contains an entry for this variant (Variation ID: 44069). 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 MYH14 protein function with a negative predictive value of 80%. 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. -
Autosomal dominant nonsyndromic hearing loss 4A Uncertain:1
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. -
not specified Benign:1
Gly1260Ser in exon 29 of MYH14: This variant is not expected to have clinical si gnificance because it is not evolutionarily conserved and some mammals, includin g mouse and rat, carry a serine (Ser) at this position. Furthermore, this varian t has been identified in 0.01% (1/8470) of European American chromosomes from a broad population by the NHLBI Exome Sequencing Project (http://evs.gs.washington .edu/EVS/; dbSNP rs200272339). -
