Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder affecting approximately 1% of the population, characterized by difficulties with social interaction and communication. Studies have identified more than 200 genes linked to ASD, particularly those involved in chromatin remodeling and synaptic neuronal connectivity (CHD8, SCN2A, NLGN3-4X, SHANK1-3). The goal of the project is to decipher the biological mechanisms underlying ASD in order to develop therapeutic strategies, using innovative preclinical models such as organoids.
