An important gene associated with Combined Oxidative Phosphorylation Deficiency 10 is MTO1 (Mitochondrial TRNA Translation Optimization 1), and among its related pathways/superpathways are tRNA processing and tRNA-uridine 2-thiolation (mammalian mitochondria). Affiliated tissues include brain, and related phenotypes are seizure and spasticity
