Researchers Try To Identify the Intelligence Gene

An anonymous reader writes "The world's largest brain study to date, with a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease. The study also uncovered new genes that may explain individual differences in brain size and intelligence. From the article: 'Following a brain study on an unprecedented scale, an international collaboration has now managed to tease out a single gene that does have a measurable effect on intelligence. But the effect – although measurable – is small: the gene alters IQ by just 1.29 points. According to some researchers, that essentially proves that intelligence relies on the action of a multitude of genes after all.'"

  1. The downside genetic engineering by crazyjj · · Score: 5, Interesting

    My intelligence is about all I have going for me. I know it's selfish, but I shudder to think of living in a world where *everyone* is smart by default. I didn't get kicked around all those years by the jocks just to settle for being an average intellect.

    Of course, I guess genetic engineering will probably turn everyone into super athletes too. But athletic prowess is a short-term thing anyway. Intellect is supposed to be for the long-term. But when/if the engineering starts, intellects (like athletes) will always be looking over their shoulders at their better engineered youngers gaining on them.

  2. For the lucky few... by MikhailValerie · · Score: 3, Interesting

    I noticed that it gets even better, if you are a child of these lucky few:

    "When people inherit C-variants from both parents they enjoy double the effect: a rise in IQ of about 2.6."

    On another note, I noticed the gene in question HMGA2 was previously linked to a person's height. I wonder if an extension of this study would consider any possible correlation between height and intelligence in regards to variations in this gene.
