Power shortage

by  /  5 August 2010

One of the largest genome-wide association studies for autism spectrum disorders, reported last week in Human Molecular Genetics, allows only one definitive conclusion: it isn’t large enough.

Deep sequencing questions role of imprinted genes in autism

by  /  8 July 2010

The mouse brain has more than 1,300 regions for which the copy from one parent is expressed more often than the one from the other parent, according to two studies published today in Science. These so-called imprinted genes have been proposed to cause some cases of autism, but the researchers say their findings do not support that theory.

New model mines simpler organisms for autism genes

by  /  3 June 2010

A new model that compares how the same genes behave in different organisms could help researchers identify previously unknown candidates for diseases such as autism. The model, published in the Proceedings of the National Academy of Sciences, takes advantage of the genetic overlap between humans and simpler organisms to discover genes associated with complex diseases.

New technique maps methylated DNA

by  /  14 May 2010

A new technique can simultaneously sequence DNA and pinpoint some of the chemical modifications that turn genes on or off, according to a report published 9 May in Nature Methods. In particular, the technique reveals methyl groups bound to DNA bases.

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.

Researchers probe genetic overlap between ADHD, autism

by  /  22 April 2010

Attention deficit hyperactivity disorder (ADHD) and autism may have more in common than childhood onset and a few similar symptoms. New research suggests the conditions share genetic roots.

Mounting evidence fingers mitochondria in autism risk

by  /  8 December 2009

Using new genetic screening technology, a few research groups are finding that a surprisingly large number of children with autism — at least five percent — have an underlying problem with their mitochondria, the energy factories of the cell.

Lessons from an obscure tumor

by  /  28 October 2009

There are well-established paternal age effects in diseases less common than autism. A new paper in Nature Genetics explains how the effects might arise, and it involves a kind of tumor you’ve probably never heard of.
