Genes affected
MYH6 (HGNC:7576): (myosin heavy chain 6) Cardiac muscle myosin is a hexamer consisting of two heavy chain subunits, two light chain subunits, and two regulatory subunits. This gene encodes the alpha heavy chain subunit of cardiac myosin. The gene is located approximately 4kb downstream of the gene encoding the beta heavy chain subunit of cardiac myosin. Mutations in this gene cause familial hypertrophic cardiomyopathy and atrial septal defect 3. [provided by RefSeq, Feb 2017]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.67).
BP6
Variant 14-23392601-C-T is Benign according to our data. Variant chr14-23392601-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 178069.
BP7
Synonymous conserved (PhyloP=-4.51 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000858 (130/151486) while in subpopulation AFR AF = 0.00308 (127/41214). AF 95% confidence interval is 0.00265. There are 0 homozygotes in GnomAd4. There are 63 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High AC in GnomAd4 at 130 AD gene.
