This cluster is known to contribute to transcriptional regulation of stem cell differentiation, aging, as well as fine-tuning of pathways involved in neuronal differentiation.Conclusions: Thus our results clearly show that neurodevelopment pathways are indeed involved in the pathophysiology of FCD. In addition, we identified a different miRNA expression signature in different FCD histological subtypes.Supported by: Capes and Fapesp.Disclosure: Dr. Avansini has nothing to disclose.
