Particularly, type II FCD – characterized by the additional presence of dysplastic neurons associated (FCD IIB) or not (FCD IIA) with balloon cells - has been shown to be associated with somatic and germline mutations in genes related to AKT, mTOR and PI3K cell signaling pathways controlling cell growth and intracortical positioning [6]. This evidence concerns the gene MTOR and fleck corneal dystrophy.
