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 made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.07359651).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000105 (16/152110) while in subpopulation EAS AF= 0.000385 (2/5194). AF 95% confidence interval is 0.0000791. There are 0 homozygotes in gnomad4. There are 6 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.3181C>T (p.R1061W) alteration is located in exon 25 (coding exon 24) of the MYH14 gene. This alteration results from a C to T substitution at nucleotide position 3181, causing the arginine (R) at amino acid position 1061 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
