Link Found Between Genetics And IQ

UPI, Feb. 27, 2007

U.S. psychiatric geneticists say they have confirmed an association between genetics and intelligence.

Washington University School of Medicine researchers in St. Louis gathered the most extensive evidence to date showing a gene that activates signaling pathways in the brain influences one kind of intelligence.

They report confirming a link between the gene CHRM2 and performance IQ, which involves a person’s ability to organize things logically.


The study’s findings are available online in Behavioral Genetics and will appear in an upcoming print issue of that journal.
