Mucopolysaccharidosis (MPS) is a group of inherited metabolic disorders caused by the absence or malfunctioning of lysosomal enzymes needed to break down glycosaminoglycans (GAGs), formerly known as mucopolysaccharides. These enzymes are crucial for the degradation of complex carbohydrates in the lysosomes. The accumulation of GAGs in various tissues and organs leads to a wide spectrum of clinical manifestations.
