The SGSH gene, also known as the sulphamidase gene, is a gene that is associated with the development of Sanfilippo syndrome type IIIA. Sanfilippo syndrome is a group of inherited diseases that are caused by genetic changes in specific genes. These changes result in a deficiency or absence of the enzyme sulphamidase, which is responsible for breaking down a complex sugar molecule called heparan sulfate.
The SGSH gene is listed in various genetic databases, including the Online Mendelian Inheritance in Man (OMIM) and PubMed. These databases provide additional information on the gene, its variants, and the related diseases. Additionally, the SGSH gene is included in the registry of genes and variants associated with specific conditions.
Testing for genetic changes in the SGSH gene can be conducted to diagnose Sanfilippo syndrome type IIIA. There are different tests available, such as DNA sequencing, to identify changes in the gene that may be causing the disease. Health professionals can refer to scientific articles, references, and resources for more information on testing and the SGSH gene.
Health Conditions Related to Genetic Changes
Genetic changes related to the SGSH gene can lead to various health conditions, including mucopolysaccharidosis type IIIA (Sanfilippo syndrome type A). These genetic changes result in a deficiency of the enzyme sulfamidase, which is responsible for breaking down a large sugar molecule called heparan sulfate.
Mucopolysaccharidosis type IIIA is a rare inherited disorder that primarily affects the central nervous system. It is characterized by progressive neurodegeneration, leading to developmental delay, cognitive decline, and behavioral problems. The severity of symptoms can vary widely among affected individuals.
To diagnose mucopolysaccharidosis type IIIA and other related diseases, genetic testing is often performed. This testing can identify changes in the SGSH gene and other genes associated with these conditions. Genetic tests can help confirm a diagnosis and provide information to guide treatment and management.
As of August 2020, the most expensive drug in America is Myalept, a drug used to treat leptin deficiency. A month’s worse of this drug costs $71, 306 per month, according to research from GoodRx. Myalept is known as an “orphan drug” because it’s intended to treat a rare disease.
Additional information and resources on health conditions related to genetic changes in the SGSH gene can be found in various databases and registries. Some of these resources include OMIM (Online Mendelian Inheritance in Man), PubMed (a database of scientific articles), and the SGSH gene entry in the Catalog of Genes and Diseases. These resources can provide detailed information on the genetic variants, associated health conditions, and available testing options.
It is important to note that the information provided here is a general overview and may not include all possible health conditions related to genetic changes in the SGSH gene. Therefore, for a comprehensive understanding of these conditions, it is recommended to consult with medical professionals and refer to the latest research and scientific literature.

Mucopolysaccharidosis type III
Mucopolysaccharidosis type III, also known as Sanfilippo syndrome, is a rare genetic disorder that affects the metabolism of complex sugars called mucopolysaccharides.
There are four subtypes of mucopolysaccharidosis type III, denoted as type IIIA, IIIB, IIIC, and IIID, each caused by mutations in different genes. Mutations in the SGSH gene are responsible for type IIIA Sanfilippo syndrome.
The SGSH gene provides instructions for making an enzyme called heparan N-sulfatase (sulfamidase). This enzyme is involved in the breakdown of a complex sugar called heparan sulfate. In individuals with SGSH gene mutations, sulfamidase activity is reduced or absent, leading to the accumulation of heparan sulfate in cells and tissues throughout the body.
Individuals with mucopolysaccharidosis type IIIA may experience progressive intellectual disability, developmental regression, behavioral problems, sleep disturbances, and physical issues such as joint stiffness and muscle weakness. The severity and specific symptoms can vary widely among affected individuals.
Genetic testing, such as sequencing of the SGSH gene, can confirm a diagnosis of mucopolysaccharidosis type IIIA. Additional laboratory tests may be done to measure sulfamidase activity or the level of heparan sulfate in the urine or blood.
There are currently no approved treatments for mucopolysaccharidosis type IIIA, but management focuses on supportive care and addressing specific symptoms. Research efforts are ongoing to develop potential therapies for this condition.
