Researchers from the University of California, San Diego School of Medicine, have investigated a series of mutations within the brain that have been commonly linked to some forms of autism. They have looked in detail at when, and where, these mutations within the genes are expressed during brain development.

They have found that these genetic mutations were turned on at various stages of fetal development, and that these act using the same pathway as two other types of genetic mutations which have been linked to autism.

Further research is necessary on these mechanisms, however, the fact that they all use the same pathway could mean that this could lead to a possible stem cell treatment for some autistic children.
