Hide & Seek Foundation for Lysosomal Disease Research

The Hide & Seek Foundation for Lysosomal Disease Research is a non-profit foundation whose mission is to raise awareness of lysosomal disease. They seek to help affected individuals and their families by marshalling the necessary forces to advance research and clinical studies, and to find a cure. Lysosomal storage diseases are inherited metabolic diseases that are characterized by an abnormal build-up of various toxic materials in the body’s cells as a result of enzyme deficiencies. There are nearly 50 of these disorders altogether, and they may affect different parts of the body, including the skeleton, brain, skin, heart, and central nervous system. New lysosomal storage disorders continue to be identified. While clinical trials are in progress on possible treatments for some of these diseases, there is currently no approved treatment for many lysosomal storage diseases. Although the signs and symptoms vary from disease to disease in this group, symptoms occur in each case because of an enzyme deficiency that inhibits the ability of the lysosomes present in each of the body’s cells to perform their normal function. The lysosomes function as the primary digestive units within cells. Their function is to break down complex components into simpler ones. Each cell has hundreds of lysosomes that degrade complex cellular components such as proteins (substrates) into simpler components. When this process does not take place, the substrate begins to accumulate in the cells. That is why these diseases are called «storage diseases». The symptoms of lysosomal storage disorders are generally progressive over a period of time.
