Sanfilippo syndrome , also known as mucopolysaccharidosis type III MPS III , is a rare autosomal recessive lysosomal storage disease that primarily affects the brain and spinal cord. It is caused by a buildup of large sugar molecules called glycosaminoglycans AKA GAGs, or mucopolysaccharides in the body's lysosomes. Affected children generally do not show any signs or symptoms at birth. In early childhood, they begin to develop developmental disability and loss of previously learned skills. In later stages of the disorder, they may develop seizures and movement disorders. Patients with Sanfilippo syndrome usually live into adolescence or early adulthood.

Mucopolysaccharidosis type III MPS III, Sanfilippo syndrome is a lysosomal storage disorder, caused by a deficiency in one of the four enzymes involved in the catabolism of glycosaminoglycan heparan sulfate. It is characterized by progressive cognitive decline and severe hyperactivity, with relatively mild somatic features. This review focuses on clinical features, diagnosis, treatment, and follow-up of MPS III, and provides information about supplementary tests and differential diagnosis.

Given that few reviews of MPS III have been published, several studies were compiled to establish diagnostic recommendations. Quantitative urinary glycosaminoglycan analysis is strongly recommended, and measurement of disaccharides, heparin cofactor II-thrombin complex and gangliosides is also used. Although there is no global consensus for treatment, enzyme replacement therapy and gene therapy can provide appropriate results.

In this regard, recent publications on treatment and follow-up are discussed. Keywords: behavioral problem; developmental delay; heparan sulfate; mucopolysaccharidosis type III. This site needs JavaScript to work properly.
