Target Background

Thick filament-associated protein located in the crossbridge region of vertebrate striated muscle a bands. In vitro it binds MHC, F-actin and native thin filaments, and modifies the activity of actin-activated myosin ATPase. It may modulate muscle contraction or may play a more structural role.
Gene References into Functions
  1. Of the 52 hypertrophic cardiomyopathy patients 11 (21.2%) had MYBPC3 variants. PMID: 29386531
  2. MYBPC3 does not seem to play a role in anthracycline induced cardiotoxicity. PMID: 29716714
  3. Mutation in MYBPC3 was identified as Restrictive Cardiomyopathy - causing mutation. PMID: 27339502
  4. pathogenic gene mutations in LMNA and MYBPC3 alter RNA splicing and may have a role in heart disease PMID: 28679633
  5. MYBPC3 mutation carriers had a high frequency of ventricular arrhythmia and syncope. An absence of family history of sudden death (SD) and past history of syncope are useful prognostic factors in patients with hypertrophic cardiomyopathy. MYH7 and MYBPC3 mutations did not significantly influence prognosis compared to non-carriers. The patients with the MYBPC3 mutation should be closely followed for the possibility of SD. PMID: 27885498

Mutations in the gene MYBPC3 coding for cardiac myosin-binding protein-C (cMyBP-C), a multi-domain protein, are the most common cause of hypertrophic cardiomyopathy ..This molecular insight suggests that key HCM-causing mutations might significantly modify the native affinity required for the assembly of the domains in cMyBP-C, which is essential for normal cardiac function. PMID: 27267291
  8. Five of the 19 patients (26.3%) had either a pathogenic variant or a likely pathogenic variant in MYBPC3 (n=1), MYH7 (n=1), RYR2 (n=2), or TNNT2 (n=1).
