Exhale: In mice with a mutated copy of the TCF4 gene (right), nerve cells (pink) are in short supply compared to controls (left). Courtesy Daniel Mulkey The breathing difficulties in children with Pitt-Hopkins syndrome, a rare form of autism, stem from dysfunctional circuitry and a malignant sodium channel in the brain stem, according to a […]

Imbalanced Characteristics: Animals with mutated ADNP have motor difficulties that are more pronounced in female mice. Photography by Rick Dahms Mice with a mutation in an autism-related gene called ADNP show gender-specific changes in gene expression, behavior, and other traits, a new study shows. The mice can mimic some of the traits seen in humans […]

Continuous Prediction: A new model that uses medical records to screen for autism is working consistently across all U.S. states, suggesting it can help overcome structural barriers such as geographical differences in medical record keeping. Courtesy Ishanu Chattopadhyay A new model of deep learning appears to outperform a widely used screening test for identifying young […]

On the move: Neurons from month-old organoids with 16p11.2 deletions (right) migrate more slowly than those from control organoids (left). Inhibiting a protein that helps cells move or change shape prevents atypical neural migration in 3D clusters of brain cells that carry genetic variants associated with autism, according to a new study. The cell models […]

Channel markers: The cerebral cortex of mice with two mutated copies of SCN2A (bottom) has fewer sodium channels (green) than that of control mice (top). Some mutations in SCN2A, a gene reliably linked to autism, change the social behavior of mice by dampening the electrical activity of their neurons, according to a new study. SCN2A […]

Extra spines: Mice with an extra copy of the MECP2 gene develop more spines on their motor cortex neurons (top) than wild-type mice during a learning task. An experimental drug normalizes this property (below). Neurons in mice with an autism-related mutation sprout outward protrusions, an overgrowth that is tracked with above-average motor learning. According to […]

Mice lacking the autism-related SHANK3 gene use more neurons to engage in social behavior than control mice, reflecting a more disorganized, less efficient signaling network in the brain, according to a new study. Mutations in SHANK3 occur in 1 to 2 percent of autistic people and can also lead to a related disorder called Phelan-McDermid […]
