About ALG11-CDG

What is ALG11-CDG?

ALG11-CDG is a gene mutation that is associated with a rare form of inherited intellectual disability. It is caused by a mutation in the ALG11 gene, which is located on chromosome 11. The mutation results in a decrease in the activity of the ALG11 enzyme, which is involved in the synthesis of glycoproteins. This can lead to a range of neurological and developmental problems, including intellectual disability, seizures, and movement disorders.

What are the symptoms of ALG11-CDG?

The symptoms of ALG11-CDG vary from person to person, but can include: developmental delay, intellectual disability, seizures, vision and hearing loss, skeletal abnormalities, heart defects, and gastrointestinal problems. Other symptoms may include poor muscle tone, poor coordination, and poor growth.

What are the causes of ALG11-CDG?

ALG11-CDG is caused by mutations in the ALG11 gene. This gene provides instructions for making an enzyme called alginate lyase, which is involved in the production of a type of carbohydrate called alginate. Mutations in the ALG11 gene lead to a shortage of functional alginate lyase, which disrupts the production of alginate and causes the signs and symptoms of ALG11-CDG.

What are the treatments for ALG11-CDG?

Currently, there is no cure for ALG11-CDG. Treatment focuses on managing the symptoms and complications of the condition. This may include physical therapy, occupational therapy, speech therapy, nutritional support, and medications to help manage seizures, pain, and other symptoms. In some cases, surgery may be recommended to correct certain physical abnormalities.

What are the risk factors for ALG11-CDG?

The risk factors for ALG11-CDG include:

1. Family history of the disorder
2. Mutation in the ALG11 gene
3. Consanguinity (marriage between close relatives)
4. Advanced maternal age
5. Exposure to certain environmental toxins or medications during pregnancy.

Is there a cure/medications for ALG11-CDG?

At this time, there is no cure for ALG11-CDG. However, there are medications that can help manage the symptoms of the disorder. These include medications to help with seizures, muscle spasms, and other neurological symptoms. Additionally, physical and occupational therapy can help improve mobility and coordination.
