Researchers have identified yet another common genetic variation that appears to be associated with autism. The results, published this week in the journal Molecular Psychiatry, show that each copy of an G at in the CACNA1G gene increase the odds of autism in boys (but not girls) by about 2.2 times.
But Stanley Nelson, senior author of the study and a 23adMe scientific advisor, points out that the G version of this SNP is actually fairly common.
“Most people with the risk genotype will not develop autism.”
