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 Benign. Variant got -20 ACMG points.

BP4

This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 2 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.81).

BP6

Variant 14-23399076-G-A is Benign according to our data. Variant chr14-23399076-G-A is described in ClinVar as [Benign]. Clinvar id is 258706.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr14-23399076-G-A is described in Lovd as [Benign].

BA1

GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.258 is higher than 0.05.
