An important gene associated with Mitochondrial Neurogastrointestinal Encephalomyopathy is TYMP (Thymidine Phosphorylase), and among its related pathways/superpathways are p53 transcriptional gene network and TP53 Regulates Metabolic Genes. Affiliated tissues include eye and brain, and related phenotypes are dysphagia and gastroesophageal reflux
