We tested the hypothesis that genetic variation in the human sodium channel gene SCN2A confers liability to idiopathic generalized epilepsy (IGE). We performed a systematic search for mutations in 46 familial IGE cases and detected three novel polymorphisms, however, allele frequencies did not differ significantly between patients and controls. A rare mutation (R1918H) was identified in one patient but was absent in one further affected family member. Thus, our results do not suggest a major role of SCN2A in the etiology of IGE.
