Brain responses to visual stimuli are smaller and weaker in children with Phelan-McDermid syndrome, an autism-linked genetic condition, than in non-autistic children.

Mice missing the autism-linked gene SHANK3 use more neurons to engage in social behavior than control mice do, reflecting a more disorganized, less efficient brain signaling network.

Merging 3D clusters of neurons that mimic different brain regions models the atypical electrical activity seen in an autism-related condition.

The autism gene SHANK3 is crucial for the development and function of muscles and the motor neurons that control them.

Doctors often conflate autism and intellectual disability, and no wonder: The biological distinction between them is murky. Scientific progress depends on knowing where the conditions intersect — and part ways.

Mice missing an autism gene called SHANK3 tend to be hypersensitive to touch, which may stem from underactivity of neurons that normally dampen sensory responses.

After a decade of working with the Phelan-McDermid Syndrome Foundation, Geraldine Bliss has co-founded a new organization to develop therapies for the condition.

Not much is known about the connection between autism and Ehlers-Danlos syndrome, a condition that affects collagen. But preliminary work provides tantalizing clues.

Mouse models of two genetic conditions related to autism show abnormalities in their movement patterns.

Finding a mutation linked to autism traits can have life-changing consequences for autistic individuals and their families.
