Additional Information:

Description: (OMIM) 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 ...
Clinical Description OMIM Plant et al. (1984) reported a mother and daughter with exercise-induced paroxysmal dystonia. The mother first developed involuntary movements of the legs after walking at age 8 years. Involvement of the upper limbs sometimes occurred with stress or continuous ...
Molecular genetics OMIM In affected members of the families reported by Margari et al. (2000) and Munchau et al. (2000), Weber et al. (2008) identified 2 different heterozygous mutations in the SLC2A1 gene (138140.0009 and 138140.0010, respectively). Two additional families with PED ...
