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]

The p.Gln1065His variant in MYH6 has been reported in 2 individuals with HCM (Ca rniel 2005, Ng 2013) and has been identified by our laboratory in 1 individual w ith HCM and 1 individual with LVNC. This variant has also been identified in 0.1 % (11/8654) of East Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs267606904). Computational prediction to ols and conservation analysis do not provide strong support for or against an im pact to the protein although the variant amino acid is present in several specie s (birds), raising the possibility that the change may be tolerated. In summary, the clinical significance of the p.Gln1065His variant is uncertain. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
