Autism exome study pinpoints mutations in brain genes

by  /  14 September 2011

Children with autism carry many more spontaneous point mutations in genes expressed in the brain compared with their unaffected siblings, according to unpublished findings presented Monday at the World Congress of Psychiatric Genetics in Washington, D.C.

New mutations spike in offspring of older fathers

by  /  12 September 2011

The offspring of older male mice are 16 times more likely to harbor a spontaneous copy number variation — a deletion or duplication of genetic material — than are the offspring of young males, according to a new study.

Studies find high rate of rare new mutations in autism

by  /  8 June 2011

Three new studies analyzing genetic data from families in which just one child has autism have found the strongest evidence yet that rare new mutations contribute to the disorder.

Family sequencing study boosts two-hit model of autism

by  /  15 May 2011

A new analysis of children with autism and their unaffected parents provides the best evidence to date that mutations in multiple genes may work together to cause autism and related disorders.

Genetics: Gene that controls methylation linked to autism

by  /  17 December 2010

A gene involved in epigenetics — regulation of gene expression by modifying DNA, but without altering the sequence — is associated with autism in families that have only one child with the disorder, according to a study published in November.

‘Daydreaming’ circuit implicated in autism, attention deficit

by  /  24 November 2010

Areas of the brain that are active when people are daydreaming or sleeping, and quiet when they are engaged in a task, are imperfectly synchronized in people with autism and attention deficit hyperactivity disorder, researchers say.

Genetics: Database of 2,000 families with autism debuts

by  /  29 October 2010

The Simons Simplex Collection (SSC), a database of genetic and clinical information from families that include one child with autism, has gathered data from more than 2,000 different families, researchers report in the October issue of Neuron.

Future of autism genetics is all in the family

by  /  30 April 2010

Two independent teams have identified the genetic culprits of three rare, inherited diseases by sequencing the genomes of several members of the same family. As the cost of whole-genome sequencing plummets, this family-based approach will reveal candidate genes not just for rare diseases but for common, complex disorders such as autism, experts say.
