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 made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MYH6. . Gene score misZ 0.85843 (greater than the threshold 3.09). Trascript score misZ 4.1282 (greater than threshold 3.09). GenCC has associacion of gene with dilated cardiomyopathy, hypertrophic cardiomyopathy, Keppen-Lubinsky syndrome, atrial septal defect 3, familial isolated dilated cardiomyopathy, hypertrophic cardiomyopathy 14.
BP4
Computational evidence support a benign effect (MetaRNN=0.14300105).
BP6
Variant 14-23389478-G-A is Benign according to our data. Variant chr14-23389478-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 180424.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=4, Uncertain_significance=1}.
BS2
High AC in GnomAd4 at 17 AD gene.
