Danon disease
Danon disease (or glycogen storage disease Type IIb) is a metabolic disorder. Danon disease is an X-linked lysosomal and glycogen storage disorder associated with hypertrophic cardiomyopathy, skeletal muscle weakness, and intellectual disability. It is inherited in an X-linked dominant pattern.
Males
In males, the symptoms of Danon disease are more severe. Features of Danon disease in males are:[citation needed]
Females
In females, the symptoms of Danon disease are less severe. Common symptoms of Danon disease in females are:[citation needed]
Although the genetic cause of Danon disease is known, the mechanism of the disease is not well understood. Danon disease involves a genetic defect (mutation) in a gene called LAMP2, which results in a change to the normal protein structure. While the function of the LAMP2 gene is not well understood, it is known that LAMP2 protein is primarily located in small structures within cells called lysosomes.[citation needed]
It is associated with LAMP2. The status of this condition as a GSD has been disputed.
Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person's medical history, symptoms, physical exam, and laboratory test results to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.[citation needed]
