Free Genetic Testing for Mitochondrial Disease
Probably Genetic + UMDF (industry-sponsored)
Patient-initiated free testing: a short online symptom quiz, then a physician-ordered at-home saliva kit with whole-genome sequencing including mitochondrial DNA, results in about 6โ12 weeks, and a free genetic counseling appointment. Probably Genetic states it conducts and funds the program itself; UMDF's patient-enabled no-cost testing program with Probably Genetic is also live.
Whole-genome sequencing covers TAFAZZIN, but the program does not name it โ families should confirm before relying on it for Barth confirmation. Carrier testing of asymptomatic relatives may also fall outside the symptom-based eligibility.
US patients and families, initiated via a symptom questionnaire with physician follow-up.
Through the Probably Genetic mito portal or UMDF's genetic testing page.
