Rare or common, inherited or spontaneous, mutations form the core of autism risk.
Neurobeachin, or NBEA, an autism–associated gene, may regulate the transport of signaling molecules to neuronal branches, according to a study published 22 November in Nature Communications.
Analyzing the organization of whole-brain structural networks could reveal differences in the way brains of children with autism and other neurodevelopmental disorders are wired.
TBL1X, a gene located on the X chromosome, is associated with autism in males but not in females, according to a study published 3 November in Molecular Autism.
A compound that boosts inhibitory signals in the brain could treat hyperactivity and excitability in mice that model fragile X syndrome, according to a study published 8 November in Developmental Neuroscience.
Head movements taint the results of many brain imaging studies, particularly those analyzing children or individuals with developmental disorders, according to two sobering new studies.
Three variants of DISC1, a gene implicated in schizophrenia and autism, may disrupt the formation of new neurons in the brain, according to a study published 17 November in Neuron.
