Glucose transporter type 1 deficiency syndrome

What causes glucose transporter type 1 deficiency syndrome?

Glucose transporter type 1 deficiency syndrome (GLUT1 deficiency syndrome) is caused by changes (mutations) in the SLC2A1 gene. This gene encodes a protein that helps transport glucose (a simple sugar) into cells where it is used as fuel. The protein is particularly important in the central nervous system since glucose is the brain's main source of energy. SLC2A1 mutations impair the function of the protein. This significantly reduces the amount of glucose available to brain cells leading to the many signs and symptoms associated with GLUT1 deficiency syndrome.

How is glucose transporter type 1 deficiency syndrome diagnosed?

A diagnosis of glucose transporter type 1 deficiency syndrome (GLUT1 deficiency syndrome) is often suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis. This may include a lumbar puncture, specialized blood tests to measure the blood concentration of glucose and genetic testing.

Is glucose transporter type 1 deficiency syndrome inherited?

Glucose transporter type 1 deficiency syndrome (GLUT1 deficiency syndrome) is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new ( __de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with GLUT1 deficiency syndrome has a 50% chance with each pregnancy of passing along the altered gene to his or her child.

How might glucose transporter type 1 deficiency syndrome be treated?

There is currently no cure for glucose transporter type 1 deficiency syndrome (GLUT1 deficiency syndrome); however, a special diet (called a ketogenic diet) may help control symptoms in some affected people. The GLUT1 Deficiency Foundation offers an information page with detailed information regarding the ketogenic diet. Please click on the link to access this resource.
