Description

Summary

The goal of this international observational study is to learn about the natural history of Danon disease in male patients >8 years of age. The key objectives include assessing change over time in cardiac structure (left ventricular mass and wall thickness), cardiac biomarkers, symptoms, and quality of life and the incidence of clinical events such as HF hospitalization, cardiac transplantation, and death.

Official Title

An Observational Study of Genetic Cardiomyopathy, Danon Disease

Details

This is an international observational study with both retrospective and prospective data collection. The study is designed to describe the natural history of Danon disease which is a rare x-linked genetic disorder and one of the most severe and penetrant forms of inherited cardiomyopathy. This study will collect data about the clinical course of Danon disease including signs and symptoms, key clinical events, and the impact of the disease on quality of life managed with current standard of care. A hybrid (retrospective and prospective data collection) approach is being taken with the aim of achieving robust and longitudinal data generation.
