Description Focal Cortical Dysplasia (FCD) is a frequent cause of drug-resistant focal epilepsy in children and young adults. The international FCD classification of 2011 has identified several clinico-pathological subtypes, either occurring isolated, i.e. FCD I or II, or in association with a principal cortical lesion, i.e. FCD III. FCD ILAE Type IIb is the most common FCD subtype and brain somatic mutations in mTOR pathway associated genes play a major pathogenic role. Herein, the aim of this study is (i) to comprehensively describe the genotype-phenotype association in twenty patients with histopathologically confirmed FCDIIb using Next Generation Sequencing (NGS) of paired blood-brain samples; (ii) we addressed for the first time the DNA methylation signature of a previously described new subtype of FCD IIId microscopically characterized by loss of cortical layer 4 in order to define their position in the molecular landscape of common FCD subtypes. These studies may also help to elucidate epileptogenic molecular mechanism of FCD.
