Welcome to the Lysosomal Learning website, an educational resource for people dealing with lysosomal storage disorders (LSDs). There are more than 40 diseases classified as LSDs, each caused by a problem with a particular enzyme in the body. While individually each of these diseases are relatively rare, grouped together they affect 1 in about every 7,700 babies born.

Symptoms vary widely across the different LSDs--some of which may cause relatively minor problems, while others can be very serious. Medical management options for the LSDs often cross several medical specialties. Some LSDs have disease-specific treatment options to consider. Be sure to speak with your doctor about the best medical care options for you or your loved ones.
