Case Discussion
Danon disease is a genetic X-linked dominant disorder. The disease is linked to genetic defects in the lysosome-associated membrane protein 2 (LAMP2) gene, encoding the LAMP2 protein.
The diagnosis in this patient was confirmed confirmed genetically and with biopsy (fibrosis with PAS positive inclusions – glycogen).
This patient died as a result of fatal arrhythmias in half a year after the diagnosis.
The case is presented together with my colleagues: Anikin A., Yarmola I. and Basargina E.
