SLC45A1 and epilepsy: Recently, a new identification method using whole-exome sequencing was developed, which included detection of rare homozygous missense variants (c.526C>T (p.Arg176Trp) and c.629C>T (p.Ala210Val)) in SLC45A1, encoding another cerebral glucose transporter which indicates that recessive mutation in SLC45A1 (second cerebral glucose transporter in addition to GLUT1) which cause intellectual disability and epilepsy.
