Heptanoate as a neural fuel: energetic and neurotransmitter precursors in normal and glucose transporter I-deficient (G1D) brain.
It has been postulated that triheptanoin can ameliorate seizures by supplying the tricarboxylic acid cycle with both acetyl-CoA for energy production and propionyl-CoA to replenish cycle intermediates. These potential effects may also be important in other disorders associated with impaired glucose metabolism because glucose supplies, in addition to acetyl-CoA, pyruvate, which fulfills biosynth...
متن کاملGLUT1 deficiency and other glucose transporter diseases.
We review the three genetically determined disorders of glucose transport across cell membranes. Diseases such as glucose-galactose malabsorption, Fanconi-Bickel syndrome and De Vivo disease (GLUT1 deficiency syndrome (GLUT1DS)) arise from heritable mutations in transporter-encoding genes that impair monosaccharide uptake, which becomes rate-limiting in tissues where the transporters serve as t...
متن کاملIntermittent Ataxia with Early Onset Absence Epilepsy in Glucose Transporter Type 1 Deficiency Syndrome.
A 4-year-old girl, born to healthy non consanguineous parents after an uneventful pregnancy and delivery with normal birth weight, presented with history of absence seizures and ataxia since 7 months of age. Absence seizures and ataxia were worse in the fasting state. She was otherwise able to walk and run, and had a normal speech. On examination, she had microcephaly (head circumference 46 cm)...
متن کاملA simple blood test expedites the diagnosis of glucose transporter type 1 deficiency syndrome
Glucose transporter type 1 (GLUT1) deficiency syndrome (GLUT1-DS) leads to a wide range of neurological symptoms. Ketogenic diets are very efficient to control epilepsy and movement disorders. We tested a novel simple and rapid blood test in 30 patients with GLUT1-DS with predominant movement disorders, 18 patients with movement disorders attributed to other genetic defects, and 346 healthy con...
متن کاملAssociation between coenzyme Q10 and glucose transporter (GLUT1) deficiency
BACKGROUND It has been demonstrated that glucose transporter (GLUT1) deficiency in a mouse model causes a diminished cerebral lipid synthesis. This deficient lipid biosynthesis could contribute to secondary CoQ deficiency. We report here, for the first time an association between GLUT1 and coenzyme Q10 deficiency in a pediatric patient. CASE PRESENTATION We report a 15 year-old girl with trun...
