Glucose Transporters (GLUTs and SGLTs) - Biochemistry Lesson. 26 Feb 2019 This article describes the glucose transporter proteins (SGLT and GLUT), which use active transport and facilitative diffusion for glucose uptake. CTD is also referred to as SLC6A8 Deficiency, CRTR, and X-linked Creatine Transporter Deficiency. Mutations in the SLC6A8 gene result in CTD. While patients  Glucose intolerance is an umbrella term for metabolic conditions which result in higher than normal blood glucose levels - hyperglycemia.

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. • GLUT1 deficiency syndrome is a metabolic disorder due to defective transport of glucose across the blood-brain barrier.

Glucose transporter deficiency

Glucose is not transported properly into the brain, which leaves it starving for the metabolic fuel it needs to grow, develop, and function the way it should. Glut1 Deficiency is caused by mutations in the SLC2A1 gene, which is responsible for regulating production of the glucose transporter protein type 1 (Glut1). Glut1 deficiency syndrome (Glut1 DS) was originally described in 1991 as a developmental encephalopathy characterized by infantile onset refractory epilepsy, cognitive impairment, and mixed motor abnormalities including spasticity, ataxia, and dystonia. The clinical condition is caused by impaired glucose transport across the blood brain barrier. 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.

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). 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.
