Chromosome 15 duplications common in autism

by  /  30 August 2012

About 1 in 500 children referred to genetic testing for undefined developmental delay, intellectual disability, or autism have duplications of the 15q11-13 chromosomal region, according to a new analysis. That makes the region the second most common large genetic alteration linked to autism.

RAS pathway, a potentially unifying theory of autism

by  /  13 March 2012

Dysregulation of the intracellular signaling pathway RAS, a risk factor for idiopathic autism, may provide a unifying theory of the disorder. Although this is not an altogether new hypothesis, several new findings have strengthened the evidence for it considerably.

Genetics: Rare mutations slightly more common in autism

by  /  5 October 2011

Duplications and deletions of genetic regions linked to autism are rare in individuals referred for genetic testing, but occur at a higher rate than in the general population.
