Promise and pitfalls of induced stem cells for autism

by ,  /  26 March 2013

Induced pluripotent stem cells, which have the ability to become any cell type, including neurons, offer a powerful way to study neuropsychiatric disorders. But for this approach to reach its full potential, researchers must first address several challenges, such as variability between cell lines, say Flora Vaccarino and Jessica Mariani.

Rho family of enzymes at crossroads of autism

by  /  12 March 2013

A number of autism risk factors converge on one cellular pathway: abnormal remodeling of the cell’s structural systems through the signaling protein Rho, says SFARI’s associate director for research, Alan Packer.

Autism-linked protein differs in male and female brains

by  /  24 January 2013

The autism-linked protein MET is expressed at lower levels in the brains of men with autism than in control brains, according to unpublished research presented Thursday at the Salk Institute, Fondation IPSEN and Nature Symposium on Biological Complexity in La Jolla, California. Women with autism do not differ from healthy controls, however.

Genetics: Intellectual disability traced to new mutations

by  /  18 January 2013

Spontaneous, or de novo, mutations are present in about half of individuals with severe intellectual disability who do not have large genetic disruptions, according to two sequencing studies published in November.

Survey says

by  /  11 January 2013

Parents who have one child with autism would like a genetic test to predict their next child’s risk of the disorder. But it’s not clear how well the tests work.
