A female heterozygous for a novel, disease causing, missense mutation in the X-linked cerebral creatine transporter (SLC6A8) gene (c.1067G > T, p.Gly356Val) presented with intractable epilepsy, mild intellectual disability and moderately reduced cerebral creatine levels. Treatment with creatine monohydrate, to enhance cerebral creatine transport, combined with l-arginine and l-glycine, to enhance cerebral creatine synthesis, resulted in complete resolution of seizures. Heterozygous SLC6A8 deficiency is a potentially treatable condition and should be considered in females with intractable epilepsy and developmental delay/intellectual disability. © 2010 Elsevier Inc.
