The study used recently developed technology to look for unusual DNA deletions or duplications — known as copy number variants or CNVs — in 996 people with autism and 1,287 matched people without autism.
People with autism didn’t have more CNVs than people without autism, and their CNVs weren’t any bigger than usual. But in autism, CNVs are much more likely to occur in gene-containing regions of the genome.
And many of the genes in which these rare CNVs occur are linked to brain function — especially the growth and maintenance of the synapses through which brain cells communicate with each other.
Bet it won’t impress Jenny McCarthy and her friends. The mission is the message, now.
