We know that carrying one specific DNA variant can increase your risk of autism. What if you carry two?
The proposed connection between premature birth and autism may be more complicated than it seems, according to a new report. Early birth may not cause classically defined autism but, rather, may predispose children to autism-like symptoms that are part of a larger syndrome, the researchers say.
Several genetic and animal studies in the past year have found intriguing ties between autism and DISC1, one of the oldest candidate genes for psychiatric disorders.
Researchers are using dogs as models of psychiatric and behavioral conditions, including obsessive-compulsive disorder and autism.
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.
The Psychiatric GWAS Consortium has released its first batch of analyses, identifying several significant common variations associated with schizophrenia. The results were presented Sunday at the World Congress of Psychiatric Genetics in San Diego.
