An important gene associated with Muscle-Eye-Brain Disease is POMGNT1 (Protein O-Linked Mannose N-Acetylglucosaminyltransferase 1 (Beta 1,2-)), and among its related pathways/superpathways are Metabolism of proteins and DREAM Repression and Dynorphin Expression. Affiliated tissues include eye and brain, and related phenotypes are eeg abnormality and gait disturbance
