Instead of a thicker muscle, genetic mutations in more than 30 genes cause the heart to grow weaker and thinner, and in turn, pump blood less efficiently. Some signs may be apparent at birth, such as cleft palate or a congenital heart defect, whereas others may only be noticed in later childhood. With these conditions, people are missing or have duplicated chromosome material.
