Genetic glitch raises autism risk

Chromosome 16 is what they are suggesting now.  I would love for them to find a cause or a set of causes that cause autism.  It would be a place to start forming real treatment.  

"They found that in people with autism, a segment of a chromosome that has genes linked to brain development and various developmental disorders was either missing or duplicated far more often. The defect was inherited in some cases, but more often the result of a random genetic accident."
