Objective: To study the DNA methylation profiles in brain tissue of patients with refractory epilepsy due to malformations of cortical development (MCDs).
Materials and Methods: Clinical, neuroimaging, and pathology characteristics were defined for 13 patients who underwent resective surgery for epilepsy. Methylation analysis was performed using Illumina® 450k Methylation Microarray. Data analysis was completed, and pathway identification was done using the R/Bioconductor package.
Results: Genes associated with Ephrin–Reelin pathway, potassium channels, and glutathione metabolism were differentially methylated in the MCD group when compared with patients who had no evidence of MCD.
Conclusions: Our preliminary data reveal that epigenetic pathways may have a role in the pathobiogenesis of MCDs.
