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 -4 ACMG points.

PP3
MetaRNN computational evidence supports a deleterious effect, 0.808
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000131 (192/1461608) while in subpopulation NFE AF = 0.000168 (187/1111858). AF 95% confidence interval is 0.000148. There are 0 homozygotes in GnomAdExome4. There are 90 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 7 AD gene.
