Impaired glucose transport across the blood brain barrier results in glucose transporter type 1 (GLUT-1) deficiency syndrome, first described in 1991. It is characterized by infantile seizures refractory to anticonvulsive treatments, microcephaly, delays in mental and motor development, spasticity, …

GLUT1 deficiency syndrome, also known as GLUT1-DS, De Vivo disease or Glucose transporter type 1 deficiency syndrome, is an autosomal dominant, genetic metabolic disorder associated with a deficiency of GLUT1, the protein that transports glucose across the blood brain barrier. Glucose Transporter Type 1 Deficiency Syndrome has an estimated birth incidence of 1 in 90,000. This birth incidence translates to an estimated prevalence of 3,000 to 7,000 in the U.S.

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. • GLUT1 deficiency syndrome is a metabolic disorder due to defective transport of glucose across the blood-brain barrier. • The classic picture is that of a child with refractory seizures starting in infancy, developmental delay, acquired microcephaly, hypotonia, and a movement disorder typically consisting of ataxia, spasticity, and dystonia. The constellation of infantile epilepsy, acquired microcephaly and hypoglychorrachia is characteristic of glucose transporter type 1 (Glut1) deficiency syndrome, a prototype neurometabolic disorder caused by inheritable mutations in the gene SLC2A1. 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.

Glucose transporter type 1 (Gl Help Milestones for Children fund research for Glucose Transporter Deficiency Syndrome (Glut1 DS), a pediatric brain energy metabolic syndrome. 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 ( 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 transporters: Structure, function and consequences of deüciency G.

• GLUT1 deficiency syndrome is a metabolic disorder due to defective transport of glucose across the blood-brain barrier. • The classic picture is that of a child with refractory seizures starting in infancy, developmental delay, acquired microcephaly, hypotonia, and a movement disorder typically consisting of ataxia, spasticity, and dystonia. GLUT1 deficiency syndrome is a disorder affecting the nervous system that can have a variety of neurological signs and symptoms. Approximately 90 percent of affected individuals have a form of the disorder often referred to as common GLUT1 deficiency syndrome.

A person with a GSD has an absence or deficiency of one of the enzymes Type I Von Gierke disease, defect in glucose-6-phosphatase)-most common type of

Glucose transporter type1 (GLUT-1) deficiency may be rare, but it is a preventable cause of severe learning difficulties; and therefore there is an urgency in making an early diagnosis. Suspicions must be roused when intractable seizures occur in infancy. These may be associated with acquired microcephaly and developmental delay.

The aim of this study was to reevaluate the role of GLUT2 in a patient with congenital GLUT2 deficiency (Fanconi-Bickel syndrome, FBS). Go to www.glut1ds.org for more information about GLUT1.

Glucose isn’t transported properly into the br ain, which creates energy issues and prevents it from growing, developing, and functioning the way it should. Deficiency of the secondary active sodium/glucose transporters result in glucose/galactose malabsorption or congenital renal glycosuriäGLUT1 deficiency produces a seizure disorder with low glucose concentration in cerebrospinal fluid and GLUT2 deficiency is the basis of the Fanconi–Bickel syndrome, which resembles type I glycogen storage disease.

Mutations in this gene impair GLUT1-mediated glucose transport across the blood brain barrier, leading to cerebral energy defi The deficiency in the transporter resulted in reduced cerebrospinal fluid glucose concentrations and reduced erythrocyte glucose transporter activities in the patients.

This causes epilepsy, movement disorders, and cognitive impairment. Treatment with ketogenic diet provides ketones as alternative energy source.

by. 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.

Deficiency of the secondary active sodium/glucose transporters result in glucose/galactose malabsorption or congenital renal glycosuriäGLUT1 deficiency produces a seizure disorder with low glucose concentration in cerebrospinal fluid and GLUT2 deficiency is the basis of the Fanconi–Bickel syndrome, which resembles type I glycogen storage disease.

The diagnosis is confirmed by genetic testing. Treatment is a ketogenic diet, as ketone bodies pass the blood-brain barrier using other transport proteins than GLUT-1. 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).

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).

From 2004-2008, 132 requests for mutational analysis of the SLC2A1 gene were studied by automated Sanger sequencing and multiplex ligation-dependent probe amplification. 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. Treatment is a ketogenic diet, as ketone bodies pass the blood-brain barrier using other transport proteins than GLUT-1.
