 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. 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.Danon disease is a type of lysosomal storage disorder.

- The Monarch Initiative brings together data about this condition from humans and other species to help physicians and biomedical researchers. Monarch’s tools are designed to make it easier to compare the signs and symptoms (phenotypes) of different diseases and discover common features. This initiative is a collaboration between several academic institutions across the world and is funded by the National Institutes of Health.
