Mitochondrial diseases are disorders caused primarily by mutations in mitochondrial DNA, with the mitochondrial 3243A > G (m.3243A > G) mutation being one of the most common pathogenic mutations. Here, a pluripotent stem cell line with high m.3243A > G mutation load was generated by reprogramming the skin fibroblasts from a patient with mitochondrial disease. This cell line exhibited pluripotency, multilineage differentiation potential and normal karyotype, representing a valuable cell resource for studying the pathogenesis of mitochondrial diseases and screening drugs.
