Robi Mitra and colleagues have developed a scalable CRISPR/Cas9 RNA sequencing assay in a human neuronal differentiation cell model, enabling high-throughput assessments of how repression of ASD risk genes affects transcription and neuronal differentiation.

Elizabeth Jonas and colleagues identified a molecular mechanism underlying the contributions of mitochondrial dysfunction to the synaptic and behavioral features associated with fragile X syndrome.

Hirofumi Morishita and colleagues showed that juvenile social isolation leads to deficits in adult mouse sociability via reduced activation of a prefrontal-paraventricular thalamus circuit.

Stefano Panzeri and colleagues used neuroimaging-derived measures to assess the sex differential impact of excitation/inhibition imbalance in idiopathic ASD.

Graeme Davis and colleagues showed that ASD risk genes genetically interact with a class of common modifiers of presynaptic homeostatic plasticity at the Drosophila neuromuscular junction.

Charles Nelson, Helen Tager-Flusberg and colleagues assessed language development in infants at high risk and low risk of ASD. They reported parental mean length of utterance as a possible difference in the high-risk group.

Gerald Crabtree, Joseph Gleeson and colleagues defined a new recessive form of ASD caused by mutations in ACTL6B, part of the BAF complex, which regulates activity-responsive transcription in resting neurons.

Jessica Cardin and colleagues identified an important and unexpected role for the VIP subclass of interneurons in mediating the functions of MeCP2 in the development of cortical circuits.
