GM2-gangliosidosis AB variant is a rare genetic condition that affects the nervous system. It is also known as GM2-gangliosidosis type AB. The condition is caused by mutations in the GM2A gene, which provides instructions for making an enzyme called beta-hexosaminidase A (Hex-A). This enzyme is involved in breaking down a type of fat molecule called ganglioside GM2.
People with GM2-gangliosidosis AB variant have a deficiency in Hex-A enzyme activity, resulting in the accumulation of ganglioside GM2 in the cells of the brain and other tissues. This build-up of ganglioside GM2 leads to progressive damage to the cells and tissues, particularly in the central nervous system. As a result, individuals with GM2-gangliosidosis AB variant experience a wide range of symptoms, including developmental delay, intellectual disability, muscle weakness, seizures, and problems with coordination and movement.
GM2-gangliosidosis AB variant is inherited as an autosomal recessive trait, which means that both copies of the GM2A gene in each cell have mutations. Parents of an individual with GM2-gangliosidosis AB variant typically carry one copy of the mutated gene and are referred to as carriers. Carriers do not show signs or symptoms of the condition.
There is currently no cure for GM2-gangliosidosis AB variant, and treatment focuses on managing the symptoms and providing supportive care. Research studies and clinical trials are ongoing to learn more about the causes, frequency, clinical features, and management of this rare condition. Additional information about GM2-gangliosidosis AB variant can be found on the OMIM database, as well as through advocacy and support groups that offer resources and information.
Frequency
The frequency of the GM2-gangliosidosis AB variant is currently unknown, as it is a rare condition. According to clinicaltrialsgov, there are no clinical trials specifically focused on this variant of GM2-gangliosidosis.
GM2-gangliosidosis is a group of genetic diseases that cause toxic accumulation of gangliosides in cells. The AB variant is one of several subtypes of GM2-gangliosidosis. It is also referred to as GM2-gangliosidosis type AB.
According to the Online Mendelian Inheritance in Man (OMIM) catalog, GM2-gangliosidosis AB variant is associated with a mutation in the GM2A gene. This gene is responsible for providing instructions to make a protein called GM2 ganglioside activator, which is involved in breaking down a specific type of lipid called gangliosides.
The inheritance pattern of the GM2-gangliosidosis AB variant is autosomal recessive. This means that an individual must inherit two copies of the mutated gene, one from each parent, in order to develop the condition.
Currently, there is limited information available on the frequency and prevalence of the GM2-gangliosidosis AB variant. As a rare condition, it is not commonly studied or reported in scientific literature. More research and testing may be needed to gather additional information on this variant of GM2-gangliosidosis and its associated genes.
Advocacy and support organizations for rare diseases, such as GM2-gangliosidosis, may provide more information and resources for patients and families affected by this condition. These organizations can provide support, education, and access to relevant clinical trials, articles, and research studies.

Causes
The GM2-gangliosidosis AB variant is caused by mutations in the GM2A gene, which provides instructions for producing beta-hexosaminidase A (beta-hex A), an enzyme involved in breaking down a type of fat molecule called gangliosides. These gangliosides are important for normal brain and nerve function.
When the GM2A gene is mutated, it can lead to a deficiency or complete absence of beta-hex A enzyme activity. Without enough functioning beta-hex A enzyme, gangliosides accumulate in the brain and nerve cells, causing the signs and symptoms of GM2-gangliosidosis AB variant.
This condition has an autosomal recessive inheritance pattern, which means that both copies of the GM2A gene in each cell must have mutations for a person to be affected. Individuals with only one mutated copy of the gene are considered carriers and typically do not experience any symptoms.
GM2-gangliosidosis AB variant is a rare condition, and the frequency of the specific gene mutations can vary among different populations. Genetic testing is available to confirm a diagnosis of GM2-gangliosidosis AB variant. It can also be used for carrier testing for at-risk individuals and for prenatal testing if both parents are known carriers.
More information about the genetic causes of GM2-gangliosidosis AB variant can be found in resources such as the Online Mendelian Inheritance in Man (OMIM) database and scientific articles found in PubMed.
For additional support and information on rare diseases, advocacy groups and patient organizations can be helpful resources. ClinicalTrials.gov is also a valuable resource for finding ongoing research studies and clinical trials related to GM2-gangliosidosis AB variant.

Inheritance
GM2-gangliosidosis AB variant has an autosomal recessive inheritance pattern. This means that both copies of the gene responsible for this condition must have mutations in order for a person to be affected.
GM2-gangliosidosis AB variant is caused by mutations in the GM2A gene. This gene provides instructions for making a protein called GM2 ganglioside activator. This protein is involved in the breakdown of a fatty substance called GM2 ganglioside. Mutations in the GM2A gene lead to a decrease or complete loss of GM2 ganglioside activator activity, which results in the toxic accumulation of GM2 ganglioside in cells throughout the body.
Researchers have identified more than 20 mutations in the GM2A gene that can cause GM2-gangliosidosis AB variant. These mutations can vary in frequency in different populations.
Genetic testing can be done to confirm a diagnosis of GM2-gangliosidosis AB variant. This testing can also determine which specific mutations are present in an affected individual.
Family members of an affected individual may also consider genetic testing to determine their carrier status. Carriers of GM2-gangliosidosis AB variant do not show symptoms of the condition but have one mutated copy of the GM2A gene. If both parents are carriers, each of their children has a 25% chance of inheriting two mutated copies of the gene and being affected by the condition.
It is important to note that GM2-gangliosidosis AB variant is a rare condition. It is estimated to affect fewer than 1 in 1 million people worldwide. Due to its rarity, there is limited information and resources available about this specific variant of GM2-gangliosidosis.
