On Cayo Santiago island, scientists track the alliances and power struggles of a colony of feral monkeys — collecting data to generate new insights into the social challenges that people with autism face.
Two seemingly similar mutations in the SHANK3 gene have divergent effects on the brain and behavior.
Many people with autism have trouble interpreting and responding to social cues. Studying how rats learn from each other can provide insights into the human social brain, says Amiel Rosenkranz.
The SHANK family of proteins, some of which are strong autism candidates, work together to facilitate brain signaling, according to unpublished results presented yesterday at the 2014 Society for Neuroscience annual meeting in Washington, D.C.
About 2 percent of people who have both autism and intellectual disability carry harmful mutations in SHANK3, a protein that helps organize the connections between neurons, according to a study published 4 September in PLoS Genetics.
A new stem-cell model of Phelan-McDermid syndrome points to a possible treatment for the rare autism-related disorder, according to a study published in Nature.
SHANK3, one of the strongest candidate genes for autism, has the potential to be a molecular entry point into understanding the synaptic, developmental and circuit origins of the disorder.
Researchers have identified deletions in SHANK1 — the third member of a gene family that is closely linked to autism — in five men with the disorder, they reported 4 May in the American Journal of Human Genetics. This is the first study linking SHANK1 mutations to people with autism.
