It is characterized by deterioration of neurological function (neurodegeneration), resulting in many of the features of the condition. This is a genetically heterogeneous group of rare, but similar in nature, diseases caused by a deficiency of one of the four lysosomal enzymes involved in the degradation of heparan sulfate. Enzyme deficiencies result in progressive storage of heparan sulfate primarily in the central nervous system, leading to severe neurodegeneration and developmental delay. Raj Mehra, PhD, Chief Executive Officer of Seelos Therapeutics provides an overview of Sanfilippo syndrome, also known as Mucopolysaccharidosis type III (MPS III), a progressive disorder that primarily affects the brain and spinal cord (central nervous system). Sanfilippo syndrome (mucopolysaccharidosis type III; MPS III) has four subtypes (A, B, C, and D) that are distinguished by four different enzyme deficiencies.

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). 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).

Sanfilippo syndrome is diagnosed by a physical examination, . • Sanfilippo syndrome is also called MPS III (Mucopolysaccharidoses type III). Sanfilippo syndrome occurs when the substances (enzymes) needed to break down the heparan sulfate sugar chain are missing or defective. Sanfilippo D is caused by the missing or deficient enzyme N-acetylglucosamine 6-sulfatase. The brain and spine are affected by all four SanFilippo syndrome subtypes. While all four subtypes ultimately result in death, there is wide variability within the population of Sanfilippo patients. Sanfilippo syndrome (MPS III) is a rare lysosomal storage disease resulting from a deficiency in one of four enzymes needed to breakdown the glycosaminoglycan heparan sulfate.

Four subtypes of Sanfilippo syndrome (A-D) have been identified based on the . Sanfilippo type A is the most severe form. Sanfilippo Syndrome (cont.) Mucopolysaccharidosis is a group of autosomal recessive metabolic disorders caused by the absence or malfunctioning of lysosomal enzymes needed to break down molecules called glycosaminoglycans - long chains of sugar carbohydrates in each of our cells that help build bone, cartilage, tendons, corneas, skin and connective tissue.Glycosaminoglycans (formerly called mucopolysaccharides) are also . Patients may also have slightly larger heads (macrocephaly) and tongues (macroglossia) than usual. MPS IIIA and MPSIIIB can both present with either severe or attenuated phenotypes. Systemic Features: Sanfilippo syndrome differs from other forms of mucopolysaccharidoses in the severity of the neurologic degeneration compared to the amount of somatic disease. MPS III (Sanfilippo syndrome) MPS III, like the other MPS conditions, was initially diagnosed by the individual having certain physical characteristics. Many Sanfilippo patients tend to develop coarse facial features. Delays in diagnosis of MPS III are common due to : - Mild physical features - Hyperactivity - Slowly progressive neurologic disease 3/1/2015 Mucopolysaccharidoses Prof.Dr.Saad S Al Ani Khorfakkan Hospital 22 rareshare.org 23. As a result, the psychomotor and cognitive development of children with this syndrome suffer greatly. • Children with Sanfilippo syndrome also have medical issues, including hearing loss, poor visual acuity, and skeletal abnormalities. The disease makes a person's body unable to appropriately break down long chains of sugar molecules referred to as, 'glycosaminoglycans.'

What is Sanfilippo Syndrome? Patients with Sanfilippo syndrome are born without symptoms and typically have normal development for the first 2 years of life. This disease is caused due to a missing or malfunctioning enzyme responsible for breakdown of glycosaminoglycans resulting in its buildup in the body causing variety of symptoms and complications. MPS III-A, or Sanfilippo syndrome type A (OMIM#252900), arises when the activity of the enzyme N-sulfoglucosamine sulfohydrolase (heparan N-sulfatase or sulfamidase; EC 3.10.1.1) is lost.

Clinically, patients have progressive neurodegeneration, behavioral problems, mild skeletal changes, and shortened life span. Sanfilippo Syndrome Clínical Guidelines I 9 The four subtypes of MPS III (A, B, C and D) are categorized into four different enzyme deficiencies in the path of heparan sulfate degradation, which in turn are caused by different mutations (Table 1). In all subtypes of this syndrome, CNS disease predominates, with. The condition belongs to a group of diseases called mucopolysaccharidoses (MPSs). In this study we describe the clinical and behavioral features of 46 children with Sanfilippo syndrome type A evaluated over a 13-year period.

Sanfilippo syndrome is a progressive disease that primarily affects the central nervous system. 1996. . significant delays occur in diagnosis due to the less pronounced facial and physical features. About Sanfilippo syndrome type B (MPS IIIB) Sanfilippo syndrome type B (MPS IIIB) is a rare and fatal lysosomal storage disease with no approved therapy that primarily affects the central nervous system and is characterized by rapid neurodevelopmental and physical decline. As there are not striking physical features accompanying the marked mental retardation of the Sanfilippo syndrome, Neulfeld and Muenzer (1995) 2 believe that it is under diagnosed, considering the high incidence found in the Netherlands (1:24 000 live births) as a result of the . The condition is a type of Mucopolysaccharidosis, or MPS, a genetic condition that causes physical abnormalities in young children and causes them to lose their neurological development. These include hyperactivity and restlessness, aggressive behavior, unusual laughing, screaming, or crying, destructiveness, mouthing and biting, lack of fear, and sleep disturbances. Hallermann-Streiff syndrome (HSS) is a rare condition with characteristic features that are present at birth and become more apparent over time. For children with more severely handicapping types of Sanfilippo syndrome, most behavior problems are likely caused by neurological MPS III is characterized by devel-opmental delay and cognitive regression, with usually mild physical problems. It's a rare disease that involves the severe and slowly progressive degeneration of the central nervous system. • Sanfilippo syndrome is a progressive, life-limiting, inherited metabolic disease. From OMIMSanfilippo syndrome B is an autosomal recessive lysosomal storage disorder characterized by the accumulation of heparan sulfate.
