The many genes implicated in Williams syndrome, a condition related to autism, may all work together to exert their effects on behavior.

Mouse models of two genetic conditions related to autism show abnormalities in their movement patterns.
Roughly one in five children who has an extra piece of chromosome 7 also meets the criteria for an autism diagnosis.
The male-dominated sex bias in autism is reversed in a related syndrome, a researcher’s gender could influence her study’s outcome, and an award-nominated ad featuring a young man with autism draws criticism.
Cells derived from the dental pulp of children with Williams syndrome hint at a treatment approach for autism.
Two studies prioritize autism risk genes for further research and illuminate how different types of mutations may work together.
Alterations to chromosome 7 lead to changes in the chemical marks that direct gene expression.
Children who carry an extra copy of part of chromosome 7 have symptoms ranging from social phobia to speech impediments. About one-third of them show signs of autism, according to the first systematic analysis of people with 7q11.23 duplication syndrome.
The branching patterns of excitatory neurons in people with Williams syndrome are roughly the opposite of the patterns seen normally, according to unpublished results from a small study presented Monday at the 2013 Society for Neuroscience annual meeting in San Diego.
The same genetic region that is missing in people with Williams syndrome is likely to be duplicated in some people with schizophrenia, according to a study published 17 July in Biological Psychiatry.
