What Is Gangliosidosis GM2 Type 2?
Gangliosidosis GM2 Type 2 is a rare and devastating genetic disorder that affects the brain and spinal cord. It’s a type of lysosomal storage disease, which means that the body is unable to break down and recycle certain fatty substances called gangliosides. As a result, these substances accumulate in the cells, leading to progressive damage and dysfunction.
Causes and Inheritance
Gangliosidosis GM2 Type 2 is caused by a deficiency of the enzyme hexosaminidase A, which is necessary for breaking down gangliosides. This deficiency is inherited in an autosomal recessive pattern, meaning that a child must inherit two copies of the mutated gene (one from each parent) to develop the condition.
The mutated gene responsible for Gangliosidosis GM2 Type 2 is the HEXA gene, which codes for the alpha subunit of hexosaminidase A. This gene is located on chromosome 15 and is responsible for producing the enzyme that breaks down gangliosides.
Prevalence and Diagnosis
Gangliosidosis GM2 Type 2 is a rare condition, affecting approximately 1 in 100,000 to 1 in 200,000 births. The diagnosis is typically made through a combination of clinical evaluation, genetic testing, and enzyme assays.
Early diagnosis is crucial, as it allows for early intervention and management of symptoms. If you suspect that your child may have Gangliosidosis GM2 Type 2, it’s essential to consult with a healthcare professional who has experience in diagnosing and managing lysosomal storage diseases.

Gangliosidosis GM2 Type 2 Causes and Risk Factors
Gangliosidosis GM2 Type 2 is a rare and devastating genetic disorder that affects the nervous system. It’s essential to understand the causes and risk factors associated with this condition to better appreciate its impact on individuals and families.
Genetic Mutation: The Primary Cause
The primary cause of Gangliosidosis GM2 Type 2 is a genetic mutation in the HEXB gene. This gene provides instructions for making the alpha-subunit of the lysosomal enzyme hexosaminidase A. The mutation leads to a deficiency of this enzyme, which is responsible for breaking down fatty substances called gangliosides in the nerve cells.
When the enzyme is deficient, gangliosides accumulate in the nerve cells, causing damage and disrupting normal cellular function. This accumulation leads to the progressive deterioration of the nervous system, resulting in the characteristic symptoms of Gangliosidosis GM2 Type 2.
Risk Factors: Who’s Affected?
Gangliosidosis GM2 Type 2 is an autosomal recessive disorder, meaning that a child must inherit two copies of the mutated gene (one from each parent) to develop the condition. The risk factors for this condition are:
- Family History: If there’s a family history of Gangliosidosis GM2 Type 2 or other lysosomal storage disorders, the risk of inheritance increases.
- Carrier Parents: If both parents are carriers of the mutated gene, each child has a 25% chance of inheriting the condition.
- Ashkenazi Jewish Descent: Individuals of Ashkenazi Jewish descent are more likely to be carriers of the mutated gene, as the mutation is more common in this population.
It’s essential for individuals with a family history of Gangliosidosis GM2 Type 2 or other lysosomal storage disorders to undergo genetic testing and counseling to understand their risk and make informed decisions about family planning.
Gangliosidosis GM2 Type 2 Diagnosis
