Description. 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. These individuals generally have frequent seizures (epilepsy) beginning in the first months of life. Inclusion Criteria: - Diagnosis of glucose transporter type I deficiency (G1D), confirmed by clinical genotyping at a CLIA-certified laboratory or by PET scan. - 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.

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.

Klinisk prövning på Glucose Transporter Type 1 Deficiency

Glucose transporter deficiency

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 energy, across the blood-brain barrier. 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). Sometimes it results sporadically from a spontaneous genetic change (not inherited) for no reason. Inclusion Criteria: - Diagnosis of glucose transporter type I deficiency (G1D), confirmed by clinical genotyping at a CLIA-certified laboratory or by PET scan.

Glucose transporter deficiency

Treatment is a ketogenic diet, as ketone bodies pass the blood-brain barrier using other transport proteins than GLUT-1. Inclusion Criteria: - Diagnosis of glucose transporter type I deficiency (G1D), confirmed by clinical genotyping at a CLIA-certified laboratory or by PET scan. - 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.

Background Carnitine transporter deficiency usually presents with cardiomyopathy and muscle weakness. It responds well to carnitine supplementation and for most of the time patients are healthy. However Glucose transporter type 1 deficiency syndrome (Glut1-DS) is characterized by infantile seizures refractory to anticonvulsants, followed by deceleration of head growth, delays in mental and motor The Invitae Glucose Transporter Type 1 Deficiency Syndrome Test analyzes the SLC2A1 gene, whose pathogenic variants cause glucose transporter type 1 deficiency syndrome (GLUT1DS), which is associated with low glucose concentration in the cerebrospinal fluid and related neurometabolic symptoms. Keywords: Glucose transporter type I deficiency, SLC2A1 gene, Coenzyme Q 10, Ataxia, Ketogenic diet Background GLUT1 deficiency syndrome (G1D) most often causes infantile-onset refractory epilepsy, cognitive impairment and motor abnormalities (ataxia, dystonia, chorea or dys-kinesia) [1-4].

Aim To define this genetic syndrome. Development The constellation of infantile epilepsy, acquired microcephaly and hypoglychorrachia is characteristic of glucose transporter type 1 (Glut1) deficiency syndrome, a prototype neurometabolic disorder caused by inheritable mutations in the gene SLC2A1. Help Milestones for Children fund research for Glucose Transporter Deficiency Syndrome (Glut1 DS), a pediatric brain energy metabolic syndrome. Children with this disorder have a myriad of physical and mental disabilities, ranging from mild to so severe that they cannot walk or talk. Glucose transporter type 1 deficiency syndrome (Glut1-DS) is characterized by infantile seizures refractory to anticonvulsants, followed by deceleration of head growth, delays in mental and motor Intervene whilst the blood glucose is still normal. 1.
