Glut1 Deficiency is a rare genetic condition that impairs brain metabolism. It is caused by mutations or variants in the SLC2A1 gene, which encodes the glucose transporter protein type 1 (Glut1). Glut1 is the principal transporter of glucose and also moves other important sugars across the blood-brain barrier.

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.

Jul 30, 2002 · Glucose transporter type 1 deficiency syndrome (Glut1 DS) usually presents as either classic Glut1 DS (~90% of affected individuals) or, more rarely, non-classic Glut1 DS (~10% of affected individuals), which comprises a broad phenotypic spectrum.

GLUT1, encoded by the SLC2A1 gene, is one of the most extensively studied of membrane transport proteins. GLUT1 has a high expression as two molecular forms of 55 and 45 kDa in brain.

The glucose transporter type 1 (Glut1) is the most important energy carrier of the brain across the blood-brain barrier. In the early nineties, the first genetic defect of Glut1 was described and known as the Glut1 deficiency syndrome (Glut1-DS).

GLUT1 is an integral membrane hydrophobic protein that comprises of 492 amino acids with a molecular weight of 54 kDa. It helps in the transport of glucose, galactose, mannose, glucosamine and ascorbic acid. It is also known as erythrocyte/brain; HepG2 GLUT protein.

Mar 8, 2025 · Glut1 Deficiency is a rare genetic condition that impairs brain metabolism. Glucose isn't transported properly across the blood brain barrier and into the brain, preventing it from growing, developing, and functioning the way it should.

GLUT1 deficiency is a rare genetic disorder. It is caused by variants in the SLC2A1 gene. SLC2A1 provides instructions for producing GLUT1. In the brain, the GLUT1 protein is involved in moving glucose from the bloodstream into the cerebrospinal fluid (CSF), which surrounds the brain. Glucose is the brain's main energy source.

A deficiency in Glut1 impairs glucose transport into the brain across the blood–brain barrier, resulting in a series of symptoms related to cerebral energy deprivation . Most Glut1DS cases are sporadic, with about 90% resulting from de novo heterozygous pathogenic variants in SLC2A1, following an autosomal dominant inheritance pattern. A ...

Jul 30, 2024 · 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.
