What is the official name of the MYOZ2 gene?

The official name of this gene is “myozenin 2.”

MYOZ2 is the gene's official symbol. The MYOZ2 gene is also known by other names, listed below.

What is the normal function of the MYOZ2 gene?

From NCBI GeneThis link leads to a site outside Genetics Home Reference.:

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]

From UniProtThis link leads to a site outside Genetics Home Reference.:

Myozenins may serve as intracellular binding proteins involved in linking Z line proteins such as alpha-actinin, gamma-filamin, TCAP/telethonin, LDB3/ZASP and localizing calcineurin signaling to the sarcomere. Plays an important role in the modulation of calcineurin signaling. May play a role in myofibrillogenesis.

How are changes in the MYOZ2 gene related to health conditions?

Genetics Home Reference provides information about familial hypertrophic cardiomyopathy, which is associated with changes in the MYOZ2 gene.
UniProtThis link leads to a site outside Genetics Home Reference. provides the following information about the MYOZ2 gene's known or predicted involvement in human disease.

Cardiomyopathy, familial hypertrophic 16 (CMH16): A hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death.[1]This link leads to a site outside Genetics Home Reference. The disease is caused by mutations affecting the gene represented in this entry.

NCBI GeneThis link leads to a site outside Genetics Home Reference. lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the MYOZ2 gene.
