A cure for Sanfilippo syndrome? A summary of current therapeutic approaches and their promise. Genetic counseling is recommended for couples who want to have children and who have a family history of MPS III. See your provider if you plan to have children and you have a family history of MPS III. Nerve damage that slowly gets worse and eventually requires wheelchair useĬall your child's provider if your child does not seem to be growing or developing normally.Symptoms are most severe in people with type A.

Some live longer, while others with severe forms die at an earlier age. Most people with MPS III live into their teenage years. MPS III causes significant nervous system symptoms, including severe intellectual disability.

More information and support for people with MPS III and their families can be found at: New research is under development for gene therapy and enzyme replacement. There is no specific treatment for this disease. Treatment of MPS III is aimed at managing the symptoms. People with MPS III have a large amount of a mucopolysaccharide called heparan sulfate in the urine. The health care provider will perform a physical exam.

Coarse facial features with heavy eyebrows that meet in the middle of the face above the nose.

Behavioral problems, including hyperactivity.

Delayed development is followed by worsening mental status. The child may have normal growth during the first few years, but final height is below average. A decline in learning ability typically occurs between ages 2 and 6. Symptoms often appear after the first year of life. People with this type are missing or do not produce enough N-acetylglucosamine 6-sulfatase.

Type D is caused by a defect in the GNS gene.

People with this type are missing or do not produce enough acetyl-CoA:alpha-glucosaminide N-acetyltransferase.

Type C is caused by a defect in the HGSNAT gene.People with this type are missing or do not produce enough alpha- N-acetylglucosaminidase. Type B is caused by a defect in the NAGLU gene.People with this type do not have a normal form of the enzyme called heparan N-sulfatase. Type A is caused by a defect in the SGSH gene and is the most severe form.The type a person has depends on which enzyme is affected. MPS III occurs when the enzymes needed to break down the heparan sulfate sugar chain are missing or defective. This is called an autosomal recessive trait. If both parents carry a nonworking copy of a gene related to this condition, each of their children has a 25% (1 in 4) chance of developing the disease. This means it is passed down through families. MPS I (Hurler syndrome Hurler-Scheie syndrome Scheie syndrome).There are several other types of MPSs, including: MPS II is also known as Sanfilippo syndrome. The condition belongs to a group of diseases called mucopolysaccharidoses (MPSs). As a result, the molecules build up in different parts of the body and cause various health problems. These chains of molecules are called glycosaminoglycans (formerly called mucopolysaccharides). Mucopolysaccharidosis type III (MPS III) is a rare disease in which the body is missing or does not have enough of certain enzymes needed to break down long chains of sugar molecules.
