Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 1P and 8B. PP3BS1BS2

The NM_001145809.2(MYH14):c.5573G>T(p.Arg1858Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000806 in 1,613,800 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1858H) has been classified as Benign.

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: Benign. The variant received -7 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.827

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000046 (7/152182) while in subpopulation AFR AF = 0.000169 (7/41446). AF 95% confidence interval is 0.0000789. There are 0 homozygotes in GnomAd4. There are 1 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 7 AD gene.
