Mucopolysaccharidosis Type IIIA, Sanfilippo Syndrome Type A, MPS IIIA
A lysosome is a structure within the cell that digests and removes waste. When the lysosome cannot recycle waste properly, the waste accumulates and causes the cell to die. Mucopolysaccharidoses (MPS) are defined by abnormal buildup of glycosaminoglycans, large sugar-protein molecules that are important for skeletal and joint function.
