Overview

Danon disease is a type of lysosomal storage disorder.[1] Lysosomes are compartments within the cell that use enzymes to break down large molecules into smaller ones that the cell can use. In Danon disease there is a defect in the wall (membrane) of the lysosome. The defect is caused by mutations in the LAMP2 gene.[2][3][1] Danon disease is chiefly characterized by cardiomyopathy (heart disease), although other signs and symptoms may occur as well. Danon disease is inherited in an X-linked fashion, as a result males tend to be more severely affected than females. Females who carry the LAMP2 gene mutation may or may not develop signs and symptoms.
