The brains of people with autism show a distinct molecular signature that reflects alterations in how genes are pieced together and expressed.

Children with an extra copy of the 15q11-13 chromosomal region, the second most common genetic abnormality in people with autism, have unusually strong brain waves called beta oscillations. The preliminary findings, presented Friday at the Dup15q Alliance Scientific Meeting in Orlando, Florida, suggest that beta oscillations could distinguish children with dup15q syndrome from those with other forms of autism.

Mice with an extra copy of the autism risk gene UBE3A have cognitive deficits and anxiety, but do not show any core features of the condition.

A new stem cell model of Angelman syndrome delivers evidence for three molecular mechanisms underlying the condition — and one potential treatment.

Unusually thin nerve fibers in the brain may underlie the motor difficulties seen in children with Angelman syndrome, an autism-related condition.

A newly discovered phenomenon in cells that regulate the sleep-wake cycle may provide clues for how to treat two autism-related conditions.

Growing up with a brother or sister on the spectrum motivates some young people to devote their careers to investigating autism.

These short reports from our reporter, Nicholette Zeliadt, give you the inside scoop on developments at the 2015 Dup15q Alliance Scientific Meeting.

Researchers are using social media and an online ‘brain-training’ program to study people with rare chromosomal abnormalities linked to autism.

An overabundance of neuronal connections in the brains of people with autism may contribute to the motor impairments associated with the disorder.
