Researchers have determined the molecular machinery that triggers normal cardiac muscle growth and survival, and have linked defects in this complex to an inherited form of human cardiomyopathy, a type of heart failure where an enlarged heart loses its ability to pump blood.

This mutation has apparently been passed down through several generations of Northern Europeans.
