Scientists uncover new risk gene for autism

by  /  2 August 2012

Several lines of converging evidence suggest that low-density lipoprotein receptor-related protein 2 (LRP2), which is involved in early patterning of the brain, is a risk gene for autism.

Focus on function may help unravel autism’s complex genetics

by ,  /  26 June 2012

To find the pathogenic mutations in complex disorders such as autism, researchers may need to conduct sophisticated analyses of the genetic functions that are disrupted, says geneticist Aravinda Chakravarti.

Autism research may require tens of thousands of samples

by  /  18 June 2012

Rare variants make up the vast majority of human genetic variation, according to two independent papers published in May in Science. That means that genetic studies of complex diseases such as autism are likely to require tens of thousands of participants.

Genetics: 2q21.1 variations link autism, attention deficit

by  /  8 June 2012

Researchers have found deletions and duplications of a small piece of chromosome 2 in individuals with autism, developmental delay, epilepsy or attention deficit hyperactivity disorder.

Genetics: Search for recessive mutations reveals autism genes

by  /  30 May 2012

By screening for recessive mutations, which are present in both copies of a gene, researchers have identified four autism candidates that may be involved in neuronal signaling, according to a study published 12 April in PLoS Genetics.

Rinse and repeat

by  /  22 May 2012

Researchers typically use only one ‘cohort,’ a group of about three dozen mice, for a given set of experiments. When others repeat the experiments with a different set of animals, sometimes the results hold up, and sometimes they don’t.

Large sequencing study ties autism genes to fragile X

by  /  26 April 2012

Children with autism carry twice as many new and damaging genetic mutations as typically developing children, according to a new study published in Neuron. The researchers also identified intriguing genetic links between autism and fragile X syndrome.

Genetics: Rare, common autism variants may function together

by  /  3 April 2012

Researchers have mapped networks of genes expressed at the same time and place in the brain and shown that rare and common autism-linked mutations are likely to function in the same pathways. The results were published 8 March in PLoS Genetics.

Genetics: Autism, Tourette syndrome genes overlap

by  /  15 February 2012

Genes implicated in Tourette syndrome overlap with those involved in autism, according to an analysis of rare DNA duplications and deletions in people with the syndrome, published in the March issue of Biological Psychiatry.
