Summaries for Glut1 Deficiency Syndrome 2

OMIM : 57 GLUT1 deficiency syndrome-2 is an autosomal dominant disorder characterized primarily by onset in childhood of paroxysmal exercise-induced dyskinesia. The dyskinesia involves transient abnormal involuntary movements, such as dystonia and choreoathetosis, induced by exercise or exertion, and affecting the exercised limbs. Some patients may also have epilepsy, most commonly childhood absence epilepsy, with an average onset of about 2 to 3 years. Mild mental retardation may also occur. One family has been reported with the additional feature of hemolytic anemia (Weber et al., 2008). GLUT1 deficiency syndrome-2 shows wide clinical variability both within and between affected families. The disorder, which results from a defect in the GLUT1 glucose transporter causing decreased glucose concentration in the central nervous system, is part of a spectrum of neurologic phenotypes resulting from GLUT1 deficiency. GLUT1 deficiency syndrome-1 (606777) represents the more severe end of the phenotypic spectrum. Correct diagnosis of GLUT1 deficiency is important because a ketogenic diet often results in marked clinical improvement in motor and seizure symptoms (reviews by Pascual et al., 2004 and Brockmann, 2009). (612126)

MalaCards based summary : Glut1 Deficiency Syndrome 2, also known as dystonia 18, is related to dystonia and paroxysmal choreoathetosis, and has symptoms including action tremor An important gene associated with Glut1 Deficiency Syndrome 2 is SLC2A1 (Solute Carrier Family 2 Member 1). Affiliated tissues include brain and thalamus, and related phenotypes are irritability and migraine

Disease Ontology : 12 A dystonia that is characterized by paroxysmal exercise-induced dyskinesia involving transient abnormal involuntary movements in the exercised limbs, and that has material basis in autosomal dominant inheritance of heterozygous mutation in the solute carrier family 2 member 1 (SLC2A1) gene on chromosome 1p34.

UniProtKB/Swiss-Prot : 74 GLUT1 deficiency syndrome 2: A clinically variable disorder characterized primarily by onset in childhood of paroxysmal exercise-induced dyskinesia. The dyskinesia involves transient abnormal involuntary movements, such as dystonia and choreoathetosis, induced by exercise or exertion, and affecting the exercised limbs. Some patients may also have epilepsy, most commonly childhood absence epilepsy. Mild mental retardation may also occur. In some patients involuntary exertion-induced dystonic, choreoathetotic, and ballistic movements may be associated with macrocytic hemolytic anemia.
