As I was researching for this paper, a picture of a small girl with a big stomach like that of a pregnant woman caught my attention. It seems that she swallowed a big balloon. But this was due to the symptoms of a genetic disease called ‘Gaucher Disease,’ named after Philippe Gaucher, a medical student from Paris. Gaucher in 1882 discovered a young woman with abnormally large cells in her spleen, and similarly, about ten years later, six years old boy was also diagnosed with same condition, which has also been named ‘Gaucher Disease,’ after Philippe Gaucher.

Within our body, many different enzymes assist in breaking up of macromolecules into smaller molecules. Gaucher Disease takes its form when an enzyme named ‘β – glucocerebrosidase’ is unable to breakdown the fatty substance into a small sugar molecule and fat molecule. This is due to the mutations of GBA gene, Glucosidase Beta Acid gene, which is located on chromosome 1, specifically base pairs 155,234,447 to 155,244,861.1 This gene encodes the enzyme ‘β – glucocerebrosidase’ that is active in lysosomes, basically a vesicle holding many enzymes responsible for breaking down the dead cells or digesting food. Since its job is critical for maintenance of basic cellular function in our bodies, we can easily find this gene across many cells under various conditions that are called ‘housekeeping gene / enzyme.’ Mutations in the GBA gene affect β – glucocerebrosidase’s activities and the related substances cannot be broken down further; thus, leading to a natural buildup of white blood cells in the liver, lungs, bone marrow, spleen, and other organs. This abnormal storage of the substances is charac...

...be advised and required. The orthopedic surgical techniques are used to relieve the pressure from damaged bony areas. And insertion of prosthetic devices is given to those whose joints have been damaged by the Gaucher disease. While bone marrow transplantations were administered as a treatment for those who are severely ill, due to high-risk procedure and requirement of precisely matched donors, this operation is performed infrequently, and otherwise reserved for the terminally ill patients. In addition to the listed therapies above, a drug named, “Zavesca” has been licensed to act as an inhibitor of one of the key enzymes responsible for the formation of glycosphingolipids, such as glucocerebroside. Also, osteoporosis and bone drugs such as “Fosamax or Alendronate, Didronel or Etidronate, and Pamidronate, are prescribed to treat Gaucher patients with bone disease.
