Out of the 69 common genes, which survived from the Bonferroni correction for the meta-analysis results (Table 1), CD3G and SLCO3A1 were validated their relevance to both epilepsy and depression by the significant alterations in GEO profiles (P < 0.05/n, n ≤ 69, Bonferroni corrected for the number of genes that appears in each GEO data set) (Table 2). Here, CD3G is linked to major depressive disorder.
