Reprogramming of two induced pluripotent stem cell clones from a patient with a novel MT-ATP6/8 mutation...

iPSC-based models are valuable for studying the mechanisms and potential treatments of mitochondrial disorders. We generated two iPSC lines from fibroblasts of a patient with a novel MT-ATP6/8 mutation (m.8570 T > C). The infant was diagnosed with a mitochondrial disease featuring cardiac hypertrophy, brain atrophy, developmental delay, and metabolic crises with elevated lactate. Mutation heteroplasmy in blood leukocytes was 95 %. Leigh syndrome-like cranial MRI abnormalities were absent at 4 months of age. We introduced reprogramming factors by Sendai virus and assessed the pluripotency of the resulting iPSCs. As control iPSC-line, we characterized the CRMi004-A line from the RUCDR repository.
