A rare genetic cause for a common medical condition

Genetic testing for inherited conditions is performed on a patient’s DNA taken from either blood, saliva and rarely skin biopsy. This information from a person’s DNA can provide diagnostic workup of rare inherited conditions and together with a comprehensive personal and family history help understand how a genetic disorder may affect them and their family.

Diagnosed with diabetes more than a decade ago, Sandy Witbeck has followed the prescribed treatment for her disease. Still, she knew something else was wrong. To find answers Sandy came to Mayo Clinic in Arizona and met with Dr. Radhika Dhamija, who completed genomic testing on Sandy’s DNA based on her personal and family history and suspicion for an inherited disorder. Tests that determined Sandy had a rare mitochondrial disorder.
