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. 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. GLUT-1 deficiency causes impaired glucose transport into the brain and erythrocytes and is a cause of seizures and progressive neurological disease in children. The cerebrospinal fluid shows low glucose concentrations (hypoglycorrhachia) to approximately 33% of the blood glucose concentration (normal 67%).

- Stable diet on no dietary therapy (i.e., no dietary therapy for 1 month). - Males and females 30 months to 17 years 11 months old, inclusive. 2015-01-01 · Yet, glucose transporter type I deficiency (G1D) remains underexplored, in part because of its apparent rarity, although this is being contested. 18 These disorders also escape conventional neurochemical interpretation. 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.

In 1991, a rare genetic disorder was first described where infants presented with developmental delays, microcephaly, hypotonia, motor development problems, and low cerebrospinal fluid glucose concentrations (hypoglycorrhachia) even in the presence of normal glycemic values, and seizures.

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 Se hela listan på epilepsy.org.uk 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.

READ PAPER. GLUT1 deficiency and other glucose transporter … The deficiency in the transporter resulted in reduced cerebrospinal fluid glucose concentrations and reduced erythrocyte glucose transporter activities in the patients.

From 2004-2008, 132 requests for mutational analysis of the SLC2A1 gene were studied by automated Sanger sequencing and multiplex ligation-dependent probe amplification. 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, … Glucose Transporter Type 1 Deficiency Syndrome also 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). Description.

Presentation of GLUT1 Transporter Deficiency. In 1991, a rare genetic disorder was first described where infants presented with developmental delays, microcephaly, hypotonia, motor development problems, and low cerebrospinal fluid glucose concentrations (hypoglycorrhachia) even in the presence of normal glycemic values, and seizures. GLUT2 DEFICIENCY. GLUT2 deficiency (MIM #227810), also known as Fanconi-Bickel syndrome, is a rare disorder of glucose homeostasis that leads to accumulation of glycogen in the liver and kidney and glucose and galactose intolerance. GLUT2 is a facilitative, bidirectional transporter. Glucose transporter type 1 deficiency syndrome (GLUT1DS) causes central nervous system dysfunction including intractable epilepsy caused by impaired glucose transport to the brain.

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.

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