What is MPS III (Sanfilippo syndrome)?

Mucopolysaccharidosis type III (MPS III), also called Sanfilippo syndrome, mainly affects the brain and spinal cord. It causes a gradual loss of nerve function, while physical features are usually mild in the early stages.^[1]

Signs begin in early childhood, often with mild developmental or speech delay and frequent ear infections. Behavior problems such as restlessness, hyperactivity and anxiety often worsen, and sleep problems are common. Over time children lose skills they had learned and may develop seizures and loss of mobility.^[1]

Physical features can include mildly coarse facial features, a large head, thick hair and eyebrows and a slightly enlarged liver or spleen. Diagnosis is confirmed with enzyme and genetic testing.^{[1, 2]}

MPS III (Sanfilippo syndrome) in the Gulf

Case reports from Saudi Arabia describe MPS III in Saudi children, including an eight-year-old girl with MPS III type B whose diagnosis was confirmed by genetic testing even though her urine test for glycosaminoglycans was normal.^[2]

Treatment options and access from the Gulf

No US-approved medicine yet. We searched the US label database (DailyMed) on 17 October 2026 and found no medicine approved specifically for MPS III (Sanfilippo syndrome).^[3] Your specialist may still prescribe approved medicines for symptoms or complications. If one of them is not available in your country, the same legal import route described below applies.

Clinical trials and expanded access. New treatments are tested in clinical trials, which you can search with your doctor on ClinicalTrials.gov. A medicine that is still investigational can only be used inside a trial or through a manufacturer's expanded-access (compassionate use) program, which the treating physician must request. We can explain how this works, but we do not supply investigational medicines.^{[4, 5]}

If a prescribed medicine is not registered. The usual legal route is a named-patient request: the treating hospital, on your specialist's written request, asks the national regulator for permission to import the medicine for one patient, using the US FDA approval as the reference. In Saudi Arabia the SFDA Special Access Program guidance covers these requests; in Bahrain, NHRA Circular 41 of 2020 sets the procedure. Other Gulf countries have their own procedures, which the hospital pharmacy confirms.^{[6, 7]} Once approval is in place, Reserve Meds arranges supply through a US-licensed pharmaceutical wholesale partner to the hospital pharmacy.

Who does what

Your treating specialist decides whether a medicine is right for the patient and writes the letter.
The hospital checks local supply, files any import request, and gives the treatment safely.
The national regulator decides whether to approve the import of a medicine that is not registered.
The manufacturer decides where its medicine can be supplied, especially for cell and gene therapies.
Reserve Meds helps organize records, coordinates US supply through our wholesale partner, shipping and updates to your family. We do not give medical advice.

Documents you will usually need

A letter from the treating specialist with the diagnosis, past treatments and why the medicine is being considered
Reports that confirm the diagnosis, such as laboratory, genetic, imaging or pathology results, translated into English where needed
Recent clinic notes and a list of current medicines
For a hospital import request: the prescription, the hospital's request form and the written consent of the patient or guardian
Proof of the US FDA approval and the US prescribing information (we can supply these)

We give you a written timeline estimate once we see the hospital file. The regulator, the treatment center and the manufacturer set their own timelines.
