Abstract: The tropomyosin-troponin complex (TTC) regulates cardiac contractility by controlling cross-bridge attachments to actin filaments based on intracellular Ca2+ levels. TTC consists of tropomyosin (TPM), cardiac troponin-T (cTnT), cardiac troponin-I (cTnI), and cardiac troponin-C (cTnC). Pathogenic variants (mutations) in genes encoding these proteins (TPM1 [TPM], TNNT2 [cTnT], TNNI3 [cTnI], and TNNC1 [cTnC]) cause different cardiomyopathy types, including hypertrophic (HCM), dilated (DCM), or restrictive cardiomyopathy (RCM).
