Lysosomal diseases are a group of inherited metabolic disorders, most of which are fatal. They are caused by defects in proteins that are critical to the function of lysosomes, which are the organelles within cells responsible for breakdown and recycling of cellular components. When this system is not functioning properly, it leads to accumulation of non-digested material within cells, ultimately leading to dysfunction and even cell death. 

The Hide & Seek Foundation was established in 2008 to find a cure for one of the most devastating lysosomal diseases, Niemann Pick Type C (NPC). The foundation was created by parents and scientists as a grassroots response to the absence of treatments for this terminal disease. There are atleast tens of thousands of families suffering from Lysosomal Diseases and related symptoms. The Hide & Seek Foundation offers cures and few therapies to lessen the severity of the symptoms of many Lysosomal disorders including:

• I-Cell disease/Mucolipidosis II

• Mucopolysaccharidoses disorders

• Pseudo-Hurler polydystrophy/Mucolipidosis IIIA

• MPSI Hurler Syndrome

• MPSI Scheie Syndrome

• MPS I Hurler-Scheie Syndrome

• Sanfilippo Type A/MPS III A

• Sanfilippo Type B/MPS III B

• Morquio Type A/MPS IVA
