The HGSNAT gene is associated with mucopolysaccharidosis III, a rare genetic disorder. Mucopolysaccharidosis III, also known as Sanfilippo syndrome, is a spectrum of conditions that affect the breakdown of long chains of sugar molecules called glycosaminoglycans (GAGs). This gene provides instructions for making an enzyme called acetyl-CoA-alpha-glucosaminide N-acetyltransferase (HGSNAT), which is involved in the degradation process of GAGs.
There are different variants of the HGSNAT gene that are related to mucopolysaccharidosis III. Mutations in this gene can lead to a deficiency or malfunctioning of the HGSNAT enzyme, causing an accumulation of GAGs in the body. This buildup can eventually lead to the characteristic signs and symptoms of mucopolysaccharidosis III, such as developmental delay, intellectual disability, and neurological problems.
Information about the HGSNAT gene, its associated mutations, and related diseases can be found in various databases and scientific resources. The Online Mendelian Inheritance in Man (OMIM) database, for example, provides detailed information on the gene, its functions, and the conditions it is associated with. Additionally, the Human Gene Mutation Database (HGMD) and PubMed have references and articles on HGSNAT and related topics.
Genetic testing can be performed to identify changes or mutations in the HGSNAT gene. This can help in the diagnosis and management of mucopolysaccharidosis III. Additional resources, such as the International Pompe Disease Registry and the Genetic and Rare Diseases Information Center (GARD), provide further information and support for individuals and families affected by mucopolysaccharidosis III.
Health Conditions Related to Genetic Changes
Genetic changes in the HGSNAT gene can lead to various health conditions. The HGSNAT gene, also known as the Heparan-Alpha-Glucosaminidase N-Acetyltransferase gene, is associated with the degradation of mucopolysaccharides.
Mutations in the HGSNAT gene are primarily linked to a disorder called Mucopolysaccharidosis Type III (MPS III), also known as Sanfilippo syndrome. There are four subtypes of MPS III, each caused by different mutations in the HGSNAT gene. MPS III is a progressive disorder that affects multiple body systems and can lead to a spectrum of health problems.
One of the most important and most popular changes to the health insurance landscape brought about by the passing of the Affordable Care Act was the prohibition against denying patients health insurance, or charging them more, if they had preexisting conditions. Research shows that 27% of Americans in the 18 to 64 age group have what would have been considered a “declinable medical condition” before the Affordable Care Act took effect, and in some regions, the percentage of patients with preexisting conditions rises to nearly four in 10, the Henry J. Kaiser Family Foundation
To learn more about the specific names and diseases related to genetic changes in the HGSNAT gene, the OMIM (Online Mendelian Inheritance in Man) database provides detailed information and catalog of genetic conditions. Additionally, PubMed – a resource for scientific articles – contains references and articles on health conditions associated with the HGSNAT gene.
For diagnostic testing and further information, genetic testing labs and clinical genetics resources can provide detailed information and resources on testing for specific genetic changes in the HGSNAT gene. The HGSNAT gene is listed and described in various genetic databases, including OMIM, Genet Testing, and NCBI Gene.
It is important to note that mutations in genes other than HGSNAT can also contribute to similar health conditions. Therefore, additional testing and evaluation may be necessary to confirm a diagnosis and determine the underlying genetic cause.

Mucopolysaccharidosis type III
Mucopolysaccharidosis type III (MPS III), also known as Sanfilippo syndrome, is a group of genetic disorders that affect the metabolism of mucopolysaccharides. This leads to the build-up of complex carbohydrates in various tissues and organs, resulting in a range of health problems.
MPS III is caused by mutations in the HGSNAT gene, which provides instructions for producing an enzyme called heparan-alpha-glucosaminide N-acetyltransferase. This enzyme is involved in the degradation of heparan sulfate, a mucopolysaccharide. Mutations in the HGSNAT gene result in a deficiency of this enzyme, leading to the accumulation of heparan sulfate in cells.
There are four subtypes of MPS III, each with a different genetic cause. These subtypes are referred to as MPS IIIA, MPS IIIB, MPS IIIC, and MPS IIID. The symptoms and severity of MPS III can vary widely, even within the same subtype.
MPS III is part of a spectrum of mucopolysaccharidoses, which are inherited disorders characterized by the gradual progressive loss of physical and mental abilities. Other types of mucopolysaccharidosis include MPS I, MPS II, MPS IV, MPS VI, and MPS VII.
To diagnose MPS III, genetic testing can be performed to identify mutations in the HGSNAT gene. This can be done using a variety of different tests, including DNA sequencing and deletion/duplication analysis. Testing for other genes related to MPS III, as well as additional genetic tests for related conditions, may also be recommended.
Information about MPS III, including its symptoms, diagnosis, and treatment, can be found in scientific articles, as well as various online databases and resources. Some of these resources include OMIM (Online Mendelian Inheritance in Man), the Genetic Testing Registry, and the Human Gene Mutation Database (HGMD).
Valstar is a disease registry and catalog of information on genetic disorders, including MPS III. The registry provides information on the genetic changes associated with each variant of MPS III, as well as references to relevant scientific articles and other resources. The Kamp and Hrebicek catalogs are also useful sources of information on MPS III and its genetic variants.
For more information on MPS III and related conditions, it is recommended to consult with a healthcare professional or genetic counselor who can provide personalized information and support.
