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]

GeneDx

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

c.2430-14C>T in intron 20 of MYH6: This variant is not expected to have clinical significance because a C>T change at this position does not diverge from the sp lice consensus sequence and is therefore unlikely to impact splicing. It has bee n identified in 0.2% (11/4406) of African American chromosomes by the NHLBI Exom e Sequencing Project (http://evs.gs.washington.edu/EVS; dbSNP rs190342289). -
