What is Sanfilippo syndrome?

Mucopolysaccaridosis type III (MPS III) is a rare genetic condition that causes fatal brain damage. It is also known as Sanfilippo syndrome and is a type of childhood dementia. MPS III is caused by a lack of an enzyme that normally breaks down and recycles a large, complex sugar molecule called ‘heparan sulphate’.

What happens when you have Sanfilippo syndrome?

Mucopolysaccharidosis type III (MPS III), also known as Sanfilippo syndrome, is a progressive disorder that primarily affects the brain and spinal cord (central nervous system). It is characterized by deterioration of neurological function (neurodegeneration), resulting in many of the features of the condition.

What are the 4 types of Sanfilippo syndrome?

Sanfilippo syndrome is divided into four subtypes, which are differentiated by their genetic cause: MPS IIIA, IIIB, IIIC, and IIID. All four subtypes of Sanfilippo syndrome primarily affect the brain and spinal cord. Over time, other body systems can also be affected.

What happens to kids with Sanfilippo?

A child born with Sanfilippo syndrome has a defect in one of the genes that make enzymes needed to break down heparan sulfate. Without the gene, the used heparan sulfate builds up in the cells and keeps them from working as they should. This can damage organs, affecting growth, mental development, and behavior.

How is Sanfilippo inherited? Everybody has two copies of each gene, one inherited from their mother, and one from their father (with some exceptions). Sanfilippo is an ‘autosomal recessive disorder’. This means that for a child to inherit Sanfilippo, he or she must get one faulty gene from each parent.
