Genes affected
MYH14 (HGNC:23212): (myosin heavy chain 14) This gene encodes a member of the myosin superfamily. The protein represents a conventional non-muscle myosin; it should not be confused with the unconventional myosin-14 (MYO14). Myosins are actin-dependent motor proteins with diverse functions including regulation of cytokinesis, cell motility, and cell polarity. Mutations in this gene result in one form of autosomal dominant hearing impairment. Multiple transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PP5
Variant 19-50281600-G-A is Pathogenic according to our data. Variant chr19-50281600-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 228877.We mark this variant Likely_pathogenic, oryginal submissions are: {Uncertain_significance=2, Likely_pathogenic=1}.
BP4
Computational evidence support a benign effect (MetaRNN=0.3606447). . Strength limited to SUPPORTING due to the PP5.
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000328 (47/1434450) while in subpopulation MID AF = 0.000238 (1/4204). AF 95% confidence interval is 0.000074. There are 0 homozygotes in GnomAdExome4. There are 25 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAd4 at 10 AD gene.

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Glu1433Lys variant in MYH14 has not been previously reported in individual s with hearing loss, but has been identified in 3/59206 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs 771755654). Although this variant has been seen in the general population, its f requency is not high enough to rule out a pathogenic role. Computational predict ion tools and conservation analyses suggest that the p.Glu1433Lys variant may im pact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of the p.Glu1433Lys variant is uncertain. -
