Confirmed versus suspected: The social significance of a genetic or non-genetic diagnosis of mitochondrial disease.

This study assessed attitudes and beliefs regarding the importance of a genetic versus non-genetic diagnosis within the mitochondrial disease community. Survey respondents were categorized into two groups - those with a genetic diagnosis, and those with a non-genetic diagnosis of mitochondrial disease. We found that while both groups perceive problems with the support available to adult mitochondrial disease patients, the non-genetic group experiences less medical and social support due to lack of a definitive diagnosis. Understanding the efficacy of existing resources for mitochondrial disease sub-groups will allow for the development or improvement of resources designed to meet patient needs.
