Results from the comparison between all patients with epilepsy and all control individuals revealed a number of genome-wide significant SNPs at 2q24.3 (p = 8.71 × 10−10), implicating SCN1A (a sodium ion channel subunit gene), and at 4p15.1 (p = 5.44 × 10−9), implicating PCDH7 (a protocadherin gene). This evidence concerns the gene SCN1A and epilepsy.
