Is smartness hereditary? Over 500 genes linked to intelligence identified

London: Being richer or smarter is something all of us aspire to be. But, turns out, it’s rooted in a person’s genes when it comes to intelligence, as per a new study released Monday. According to the study, researchers from the University of Edinburgh, University of Southampton, and Harvard University have identified some 538 genes that appear to be linked to sharp intelligence. In fact, the team not only found 538 genes related to intellectual ability but also identified 187 regions in the human genome that are linked to thinking skills.

For the research that was aimed at finding out which genes are associated with intelligence, the researchers compared variation in DNA in more than 240,000 people from around the world. Meanwhile, some genes linked to intelligence are also associated with living longer, said the study. Read: 17 new genes linked to longer lifespan identified

“Our study identified a large number of genes linked to intelligence,” said Dr David Hill, from the University of Edinburgh’s Centre for Cognitive Ageing and Cognitive Epidemiology, said in a statement. “Importantly, we were also able to identify some of the biological processes that genetic variation appears to influence to produce such differences in intelligence, and we were also able to predict intelligence in another group using only their DNA.”

“This study adds to what we know about which genes influence intelligence, and suggests that health and intelligence are related in part because some of the same genes influence them, ” said one of the authors Professor Ian Deary from the University of Edinburgh.
