We report three Japanese patients with glucose transporter type 1 deficiency syndrome (Glut1DS). Two patients had a normal erythrocyte 3-O-methylglucose (3OMG) uptake, one with a previously reported T295M substitution and the other with a novel 12-bp insertion at nt 1034–1035, ins CAGCAGCTGTCT. The third patient, with deficient 3OMG uptake, had a previously reported hot-spot mutation, R333W. All three patients responded to a ketogenic diet. All patients showed a significant improvement in ataxia, with blood β-hydroxybutyrate (BOHB) levels ranging from 0.1 to 3 mM. BOHB levels of at least 3 mM were necessary to control seizures, and higher ketone levels are recommended to meet brain energy needs during development. FDG-PET scan, performed before and after a ketogenic diet in the R333W patient, did not change despite a clinical improvement. This clinical condition is treatable and early diagnosis is important.
