Spectrum is covering the 2020 International SYNGAP1 Scientific Conference, which took place virtually because of the coronavirus pandemic. Here we’re highlighting researchers’ reactions to noteworthy presentations.

Mice with mutations in the autism-linked gene SYNGAP1 have trouble sensing touch, which may stem in part from brain-circuit alterations and dulled alertness.

A gene-editing treatment shows long-lasting effects in a mouse model of Angelman syndrome, a genetic condition related to autism.

A tool that relies on video cameras and machine learning can identify mice that have mutations in a top autism gene by their behaviors. It also detects how a widely used autism drug affects their movements.

Mice missing an autism gene groom themselves more than usual and have altered circadian rhythms after nighttime exposure to light.

A new treatment curbs deadly seizures in a mouse model of Dravet syndrome, a severe form of epilepsy.

Autistic people and their families are increasingly experimenting with marijuana to try to ease problems such as insomnia, epilepsy and chronic pain — and traits of autism. But there is little evidence for its safety or effectiveness.

A new method that suppresses gene expression in the embryos of fish and mice may help researchers study autism genes in early development.

Mice missing the autism gene NLGN3 have altered social behaviors and brain responses to the hormone oxytocin, both of which improve after treatment with a drug that helps regulate protein production.

An experimental drug silences a DNA segment and seems to prevent seizures and death in a condition related to autism.
