MYBPC3 and dilated cardiomyopathy: ALKO presented a typical dilated cardiomyopathy profile with a remarkable reduction in four sarcomere genes (myosin heavy chain 7-like,actin alpha cardiac muscle 1b,myosin binding protein C3, and troponin T type 2a) and two Ca2+ handling regulator genes (tropomyosin 4b and ATPase sarcoplasmic/endoplasmic reticulum Ca2+ transporting 2b).
