Sequence and structure of a human glucose transporter. Current Management and Future Approaches”. Once diagnosed, a ketogenic diet is usually recommended as it helps to control seizures. Diagnosis is based on the clinical picture and biochemical analysis of the cerebrospinal fluid CSF. Glucose transporter type 1 GLUT1 deficiency syndrome is characterized by an encephalopathy marked by childhood epilepsy that is refractory defifiencia treatment, deceleration of cranial growth leading to deficiendia, psychomotor retardation, spasticity, ataxia, dysarthria and other paroxysmal neurological phenomena often occurring before meals.

From Wikipedia, the free encyclopedia.

Variations on the ketogenic diet, including the Modified Atkins Diet, and diets based on MCT oil have also been shown to be beneficial for some Glut1 Deficiency patients. Cloning and functional expresssion in bacteria of a novel glucose transporter present in liver, intestine, kidney, and B-pancreatic islet cells. It is plausible to propose that the modulation of GLUT4 is triggered by a combination of factors indicating cellular sensitiveness to insulin.

Nucleotide sequence of putP, the proline carrier of Escherichia coli K Reduced content and preserved translocation of glucose transporter GLUT 4 in white adipose tissue of obese mice.

There is growing empirical evidence that these diets can provide at least some of the benefits of the classical ketogenic diet for some Glut1 Deficiency patients.

When metabolized by the body, C7 oil produces ketones similar to those produced on a ketogenic diet in addition to other types of ketones that are thought to fulfill further metabolic requirements in the absence of sufficient glucose.

Mol Genet ; Defixiencia esters have been shown in recent research to improve seizures and movement disorders in Glut1 deficient mice, but human studies have not yet been conducted. In familial renal glycosuria, the participation of SGLT2 and SGLT1 seems to be fundamental, either by loss of transport capacity or by decrease in the transporter affinity.
