Paroxysmal Exercise-induced Dyskinesias Caused by GLUT1 Deficiency Syndrome

Tremor Other Hyperkinet Mov (N Y). 2016 Mar 4:6:371. doi: 10.7916/D89W0F96. eCollection 2016.

Abstract

Background: Glucose transporter type 1 deficiency syndrome is due to de novo mutations in the SLC2A1 gene encoding the glucose transporter type 1.

Phenomenology shown: Paroxysmal motor manifestations induced by exercise or fasting may be the main manifestations of glucose transporter type 1 deficiency syndrome.

Educational value: Proper identification of the paroxysmal events and early diagnosis is important since the disease is potentially treatable.

Keywords: GLUT1 deficiency; Paroxysmal exercise-induced dyskinesia; SLC2A1; dystonia; epilepsy.
