Fanconi-Bickel Syndrome, also known as glycogen storage disease due to lactate dehydrogenase m-subunit deficiency, is related to glycogen storage disease and neonatal diabetes, and has symptoms including muscle cramp, muscle rigidity and muscular stiffness. An important gene associated with Fanconi-Bickel Syndrome is SLC2A2 (Solute Carrier Family 2 Member 2), and among its related pathways/superpathways are Metabolism and PI3K-Akt signaling pathway. Affiliated tissues include liver and spleen, and related phenotypes are failure to thrive and hypophosphatemia
