New tests for fragile X promise routine screening

by  /  11 October 2010

A new wave of genetic tests for fragile X syndrome, the leading cause of inherited mental retardation and the most common genetic cause of autism, may make it possible to routinely screen pregnant women and newborns for the syndrome.

Risky secrets

by  /  30 August 2010

For a few hundred dollars and a bit of your spit, you can have parts of your DNA analyzed. If you’re more ambitious, $20,000 — and a lot less than that a year from now — will buy you the sequence of your entire genome. But the real question is should you, and others like you, find out what secrets your genome holds?

Microarray analysis deemed best genetic test for autism

by  /  28 May 2010

Chromosomal microarray analysis, which screens the entire genome for tiny blips in the sequence, should be the first genetic test performed when diagnosing autism, says a consortium of clinical geneticists. The recommendation comes on the heels of a study that found the test is three times more effective at spotting autism variants than are standard clinical methods.

Rare deletions on chromosome 16 tie autism to obesity

by  /  10 February 2010

Individuals who carry a large and rare deletion on chromosome 16 that is associated with autism are likely to have developmental delays, be obese or both, according to two studies published last week in Nature.

Only subset of chromosome 16 variants linked to autism

by  /  20 November 2009

Deletions or duplications of chromosomal segment 16p11.2 — previously reported as a key autism region — are seen in people with developmental delays and speech and behavioral problems, but not necessarily autism. That’s the finding from two large studies published last week of people carrying these rare genetic variations.

Variants associated with autism over-hyped, company says

by  /  6 November 2009

Variations linked to autism and schizophrenia crop up in people with a large variety of conditions, including bipolar disorder, seizures and obsessive-compulsive disorder, as well as in healthy people. This notion gained new support from unpublished data presented at the World Congress for Psychiatric Genetics in San Diego.
