Glucose transporter type 1 ( GLUT1) deficiency syndrome (GLUT1DS, OMIM 606777) is caused by impaired glucose transport into brain mediated by GLUT1, the glucose transporter at the blood–brain barrier. The condition is diagnosed by hypoglycorrhachia, impaired glucose uptake into erythrocytes, and heterozygous mutations in the SLC2A1 gene (OMIM

The purpose of this protocol is to create a registry for patients diagnosed with Glucose Transporter Type 1 Deficiency (G1D), or patients experiencing symptoms consistent with G1D but not yet diagnosed, to enter medical information for physicians and other health researchers to analyze to increase the understanding of G1D and any sub-diagnoses.

Glut1 is the principal transporter of glucose, the primary source of Glucose transporters: Structure, function and consequences of deüciency G. K. BROWN Genetics Unit, Department of Biochemistry, South Parks Road, Oxford, OX1 3QU, UK. E-mail: gkb=bioch.ox.ac.uk Summary: There are two mechanisms for glucose transport across cell mem-branes. In the intestine and renal proximal tubule, glucose is transported Glucose transporter type 1 deficiency is caused by mutations of the SLC2A1 gene which is most frequented inherited as an autosomal dominant (the gene is located on one of the nonsex chromosomes of either parent and 50% of the children will be affected). Glucose transporter type 1 ( GLUT1) deficiency syndrome (GLUT1DS, OMIM 606777) is caused by impaired glucose transport into brain mediated by GLUT1, the glucose transporter at the blood–brain barrier. The condition is diagnosed by hypoglycorrhachia, impaired glucose uptake into erythrocytes, and heterozygous mutations in the SLC2A1 gene (OMIM Glucose transporter type 1 deficiency syndrome (GLUT1DS) is characterised by deficient glucose transport over the blood-brain barrier and reduced glucose availability in the brain. This causes epilepsy, movement disorders, and cognitive impairment. Treatment with ketogenic diet provides ketones as alternative energy source.

Please check the synonyms listing to find the alternate name(s) and disorder subdivision(s) covered by this report. Glucose transporter type 1 (Gl The purpose of this protocol is to create a registry for patients diagnosed with Glucose Transporter Type 1 Deficiency (G1D), or patients experiencing symptoms consistent with G1D but not yet diagnosed, to enter medical information for physicians and other health researchers to analyze to increase the understanding of G1D and any sub-diagnoses. Glucose Transporter Type 1 Deficiency Syndrome (Glut1 DS) is a rare disease with an estimated birth incidence of 1 in 90,000 (Coman, 2006).

Heterozygous variation in solute carrier family 2, facilitated glucose transporter member 1 (SLC2A1) and mutations of the GLUT1/SLC2A2 gene results in the failure of glucose transport, which is related with a glucose type-1 transporter (GLUT1) deficiency syndrome (GLUT1DS).

In the intestine and renal proximal tubule, glucose is transported GLUT-1 deficiency syndrome should be suspected in children with epilepsy-like seizures and delayed development combined with a low content of glucose in spinal fluid. The diagnosis is confirmed by genetic testing.

Glucose transporter type 1 deficiency does not have a cure. Common treatments include following a ketogenic diet, which is a high-fat, low-carbohydrate diet. Thioctic acid administration may also help some, with symptomatic and supportive care. Genetic counseling may be of benefit to affected families.

Children with this disorder have a myriad of physical and mental disabilities, ranging from mild to so severe that they cannot walk or talk. Glut1 DS was first discovered in 1991 by Dr. Darryl DeVivo at the Colleen Giblin Laboratories, Columbia Glucose Transporter 2 Deficiency: Fanconi–Bickel Syndrome Glucose transporter 2 (GLUT-2) facilitates the transport of glucose and galactose across the cell membranes of … Glucose transporter type 1 deficiency syndrome (GLUT1DS) is characterised by deficient glucose transport over the blood‐brain barrier and reduced glucose availability in the brain. This causes epilepsy, movement disorders, and cognitive impairment. Treatment with ketogenic diet provides ketones as alternative energy source. The pattern of expression of the GLUT transporters in different tissues is related to the different roles of glucose metabolism in different tissues. Primary defects in glucose transport all appear to be extremely rare and not all possible deficiencies have been identified.

Glucose Transporter Type 1 Deficiency Syndromealso known as Glut1DS, G1D, De Vivo Disease. Glut1 Deficiency is a rare genetic condition that affects brain metabolism. It is caused by a mutation in the SLC2A1 gene, which regulates the glucose transporter protein type 1 (Glut1). Glut1 is the principal transporter of glucose, the primary source of

Mutations in this gene impair GLUT1-mediated glucose transport across the blood brain barrier, leading to cerebral energy deficiency. Test description. The Invitae Glucose Transporter Type 1 Deficiency Syndrome Test analyzes the SLC2A1 gene, whose pathogenic variants cause glucose transporter type 1 deficiency syndrome (GLUT1DS), which is associated with low glucose concentration in the cerebrospinal fluid and related neurometabolic symptoms. GLUT1 deficiency and other glucose transporter diseases.

Inclusion Criteria: - Diagnosis of glucose transporter type I deficiency (G1D), confirmed by clinical genotyping at a CLIA-certified laboratory or by PET scan. - Stable diet on no dietary therapy (i.e., no dietary therapy for 1 month). - Males and females 30 months to 17 years 11 months old, inclusive.

Heterozygous variation in solute carrier family 2, facilitated glucose transporter member 1 (SLC2A1) and mutations of the GLUT1/SLC2A2 gene results in the failure of glucose transport, which is related with a glucose type-1 transporter (GLUT1) deficiency syndrome (GLUT1DS); this affects the transport of glucose across the blood–brain barrier and its availability in the brain [16,17]. Summary. Glucose transporter type 1 deficiency syndrome (Glut1DS) is a rare genetic metabolic disorder characterized by deficiency of a protein that is required for glucose (a simple sugar) to cross the blood-brain barrier and other tissue barriers. The most common symptom is seizures (epilepsy), which usually begin within the first few months of 2015-12-07 · Glucose transporter type 1 deficiency syndrome (GLUT1 deficiency syndrome) is an inherited condition that affects the nervous system. Signs and symptoms generally develop within the first few months of life and may include recurrent seizures (epilepsy) and involuntary eye movements.

This birth incidence translates to an estimated prevalence of 3,000 to 7,000 in the U.S. Glut1 DS is a debilitating disease characterized by seizures, movement disorders and developmental delay (Pearson, 2013). Glucose transporter type 1 deficiency does not have a cure. Common treatments include following a ketogenic diet, which is a high-fat, low-carbohydrate diet. Thioctic acid administration may also help some, with symptomatic and supportive care. Genetic counseling may be of benefit to affected families.
