Entrez Gene Summary for MYH6 Gene

  • 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 ~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, Mar 2010]

GeneCards Summary for MYH6 Gene

MYH6 (Myosin, Heavy Chain 6, Cardiac Muscle, Alpha) is a Protein Coding gene. Diseases associated with MYH6 include atrial septal defect 3 and sick sinus syndrome 3. Among its related pathways are RhoGDI Pathway and ERK Signaling. GO annotations related to this gene include actin binding and calmodulin binding. An important paralog of this gene is MYH4.

  • Muscle contraction

Tocris Summary for MYH6 Gene

  • Myosins are a large family of motor proteins that share the common features of ATP hydrolysis, actin binding and potential for kinetic energy transduction. Originally isolated from muscle cells (hence the name), almost all eukaryotic cells are now known to contain myosins. Structurally, mysoins contain a head domain that binds to actin filaments (microfilaments) and is the site of ATP hydrolysis. The tail domain interacts with cargo molecules, and the neck acts as a linker between the head and tail and is the site of regulatory myosin light chain binding. There are 17 myosin families and the most well characterized is myosin II. Myosin II is found predominantly in myocytes and mediates plus-ended movement along microfilaments. It is involved in muscle contraction through cyclic interactions with actin-rich thin filaments, creating a contractile force. It is regulated by phosphorylation via myosin light chain kinase (MLCK) and by intracellular Ca2+ concentrations.

Disorders for MYH6 Gene

(4) OMIM Diseases for MYH6 Gene (160710)


  • Atrial septal defect 3 (ASD3) [MIM:614089]: A congenital heart malformation characterized by incomplete closure of the wall between the atria resulting in blood flow from the left to the right atria. {ECO:0000269 PubMed:15735645}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Cardiomyopathy, familial hypertrophic 14 (CMH14) [MIM:613251]: 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. {ECO:0000269 PubMed:11815426, ECO:0000269 PubMed:15998695}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Cardiomyopathy, dilated 1EE (CMD1EE) [MIM:613252]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. {ECO:0000269 PubMed:15998695}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Sick sinus syndrome 3 (SSS3) [MIM:614090]: The term sick sinus syndrome encompasses a variety of conditions caused by sinus node dysfunction. The most common clinical manifestations are syncope, presyncope, dizziness, and fatigue. Electrocardiogram typically shows sinus bradycardia, sinus arrest, and/or sinoatrial block. Episodes of atrial tachycardias coexisting with sinus bradycardia (tachycardia-bradycardia syndrome) are also common in this disorder. SSS occurs most often in the elderly associated with underlying heart disease or previous cardiac surgery, but can also occur in the fetus, infant, or child without heart disease or other contributing factors. {ECO:0000269 PubMed:21378987}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry. The lifetime risk of being diagnosed with sick sinus syndrome is higher for carriers of variant p.Arg721Trp than for non-carriers. {ECO:0000269 PubMed:21378987}.
