Prognosis The prognosis is sqnfilippo with death occurring in most cases of type IIIA at the end of the second decade. Only comments written in English can be processed. In early childhood, they begin to develop developmental disability and loss of previously learned skills. The flavonoid genistein decreases the pathological accumulation of glycosaminoglycans in Sanfilippo syndrome.

The neurological degradation accompanied by multiple complications requires a multidisciplinary management to allow adapted symptomatic treatment. GAGs are stored in the cell lysosome, and degraded by glycosidases, sulfatases and acetyltransferases. Although the missing enzyme can be manufactured and given intravenously, it cannot penetrate the blood—brain barrier and therefore cannot treat the neurological manifestations of the disease.

Bumps, bruises, or ear infections that would be painful for other children often go unnoticed in children with MPS III. Additional information Further information on this disease Classification s 7 Gene s 4 Clinical signs and symptoms Publications in PubMed Other website s Asnfilippo is caused by a deficiency in one of the enzymes needed to break down the glycosaminoglycan GAG heparan sulfate which enfermefad found in the extra-cellular matrix and on cell surface glycoproteins.

The frequency of the different subtypes varies between countries: Views Read Edit View history.

Sanfilippo syndrome: Overall review.

Diagnostic methods Diagnosis is based on detection of increased levels of heparan sulfate HS in urine. The following discussion is therefore applicable to all four conditions.


Individuals with MPS III tend to have mild skeletal abnormalities; osteonecrosis of the femoral head may be present in patients with the severe form. The stiff joints, hirsuteness and coarse hair typical of other mucopolysaccharidoses are usually not present until late in the disease.

When placing this tag, consider associating this request with a WikiProject. In the final phase of the illness, children become increasingly immobile and unresponsive, often require wheelchairs, and develop swallowing difficulties and seizures. Other search option s Alphabetical list. The diagnosis may be confirmed by assay of enzyme levels in tissue samples and gene sequencing. Along with many other lysosomal storage diseasesMPS-III exists as a model of a monogenetic disease involving the central nervous system.

Health care resources for this disease Expert centres Diagnostic tests Patient organisations 70 Orphan drug s GAGs are attached to serine and threonine at the surface of proteoglycans, which are found in the extracellular matrix and the cell membrane, or stored in the secretory granules.

A total of mutations that causes this form of Sanfilippo syndrome have been found so far. All four subtypes of Sanfilippo syndrome have autosomal recessive inheritance.

The life-span of an affected child does not usually extend beyond late teens to early twenties. For all other comments, please send your remarks via contact us.

Diagnosis is based on detection of increased levels of heparan sulfate HS ssanfilippo urine. For any future treatment to be successful, it must be administered as early as possible.


Impaired enzymatic activities are efnermedad to multiple mutations. Incidence of Sanfilippo syndrome varies geographically, with approximately 1 case perlive births in Northern Ireland, [17] 1 per 66, in Australia, [18] and 1 per 50, in the Netherlands. The disease manifests in young children.

In later stages of the disorder, they may develop seizures and movement disorders. The prognosis is poor with death occurring in most cases of type IIIA at the end of the second decade.

Pediatrics International, 57 3 A few cases of attenuated forms have also been reported. Other characteristics include coarse facial features, thick lips, synophrys, and stiff joints. When mutations have been identified in the index patient, heterozygous individuals in the family can be accurately detected.

As affected children have normal muscle strength and mobility, the behavioural disturbances are very difficult to manage.
