Although the description of Crohn's disease is by far his most famous accomplishment, Crohn had a long career both as a clinician, and as a researcher who contributed to modern understanding of many gastrointestinal conditions. Crohn received his bachelor's degree from City College of New York in 1902. He received a medical degree from Columbia University College of Physicians and Surgeons in 1907.

Glycogen storage disease type IV the gene but show no symptoms of the disease. It affects 1 in 800,000 individuals worldwide, with 3% of all Glycogen Storage Diseases being type IV. It is a result of the absence of the glycogen branching enzyme, which is critical in the production of glycogen. This leads to very long unbranched glucose chains being stored in glycogen. The long unbranched molecules have a low solubility which leads to glycogen precipitation in the liver. These deposits subsequently build up in the body tissue, especially the heart and liver. The inability to breakdown glycogen in muscle cells causes muscle weakness. The
