Study Overview
Brief Summary
Autism Spectrum Disorder refers to complex neuro-developmental disorders that affect social communication and behavioral adaptation. Currently, the diagnosis of Autism Spectrum Disorder is based on a clinical examination that is performed classically during the first three years of life. The heterogeneity of the disorders occurring in autism make pathologies difficult to diagnose and manage.
The overall goal of this project is the identification of metabolic biomarkers based on clinical profile. The best characterization of physiopathological pathways will ultimately allow the identification of subgroups of subjects and facilitate the development of targeted therapeutics.
The proposed work aims to test the hypothesis of a disruption of tryptophan metabolism in Autism Spectrum Disorder via the gut microbiota.
Detailed Description
Autism Spectrum Disorder refers to complex neuro-developmental disorders that affect social communication and behavioral adaptation. In France, Autism Spectrum Disorderaffects about 1 in 100 people according to international criteria and is diagnosed in early childhood. Currently, the diagnosis of Autism Spectrum Disorder is based on a clinical examination that is performed classically during the first three years of life. The heterogeneity of the disorders occurring in autism make pathologies difficult to diagnose and manage.
The overall goal of this project is the identification of metabolic biomarkers based on clinical profile (based on behavioral and cognitive markers). The best characterization of physiopathological pathways (from the molecular scale to the phenotypic scale) will ultimately allow the identification of subgroups of subjects and facilitate the development of targeted therapeutics.
The proposed work aims to test the hypothesis of a disruption of tryptophan metabolism in Autism Spectrum Disorder via the gut microbiota.
