Ordering Recommendation

Assess for sequence variants in the mitochondrial genome (mtDNA) causing mitochondrial disorders, especially for individuals with clinical symptoms characteristic of a specific disorder, such as leber hereditary optic neuropathy (LHON), mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS), myoclonic epilepsy with ragged-red fibers (MERRF), and neurogenic weakness with ataxia and retinitis pigmentosa (NARP).
