Genes affected

MYOZ2 (HGNC:1330): (myozenin 2) The protein encoded by this gene belongs to a family of sarcomeric proteins that bind to calcineurin, a phosphatase involved in calcium-dependent signal transduction in diverse cell types. These family members tether calcineurin to alpha-actinin at the z-line of the sarcomere of cardiac and skeletal muscle cells, and thus they are important for calcineurin signaling. Mutations in this gene cause cardiomyopathy familial hypertrophic type 16, a hereditary heart disorder. [provided by RefSeq, Aug 2011]

The p.Pro217Thr variant in MYOZ2 has not been previously reported in individuals with cardiomyopathy, but has been identified in 2/16510 South Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Com putational prediction tools and conservation analysis do not provide strong supp ort for or against an impact to the protein. In summary, the clinical significan ce of the p.Pro217Thr variant is uncertain. -
