[Inherited heart diseases and storage diseases with cardiac involvement]

Rare diseases mostly have a genetic cause. Many rare cardiovascular diseases also have a genetic cause. For target-oriented cardiogenetic diagnostics, expert knowledge in human genetics as well as in clinical cardiology is needed. In recent years, the genetic cause of a number of heart diseases have been, at least in part, elucidated. Especially, certain arrhythmias and cardiomyopathy forms have a monogenetic cause. An early genetic diagnosis means that patients can be treated more effectively. Rare storage diseases also usually have a genetic cause and can manifest themselves in the heart; prominent examples are Fabry disease and amyloidosis. As patients with Fabry disease or amyloidosis suffer from a diverse and variable symptomatology, the correct diagnosis is often difficult.
