In contrast, BMD showed increased levels of tricarboxylic acid (TCA) cycle and of respiratory chain proteins like Succinate dehydrogenase A (SDHA), Succinate Co‐A ligase beta (SUCLA2), ATP synthase alpha (ATP5A1), gamma (ATP5C1), and d subunit (ATP5B) compared with DMD and controls (Figure3B). The gene discussed is SDHA; the disease is Duchenne muscular dystrophy.
