Over 500 genes associated with intelligence identified by scientists

Some genes linked to intellectual ability are also associated with living longer, scientists found.

Scientists have identified over 500 genes linked to intelligence after comparing DNA variations in more than 240,000 people from around the world.

Previous studies have suggested that between 50 per cent and 75 per cent of intelligence is inherited, and the rest comes through upbringing, friendship groups and education.

Researchers have identified 538 genes that can influence how clever people are - and say they can be obtained using a simple mouth swab.

Five Hundred and Thirty-eight (538) genes that play roles in intellectual ability have been identified by a team of global researchers, according to a study released on Monday by the University of Edinburgh.

Those that contributed to problem-solving powers boosted the process by which neurons carry signals from one place to another in the brain. When they analysed the DNA of a group of different people, the team were only able to predict 7 per cent of the intelligence differences between those people.

The study was aimed at finding out which genes are associated with intelligence.

"Our study identified a large number of genes linked to intelligence", said David Hill from University of Edinburgh.

People who expressed the genes were less likely to suffer from Alzheimer's, depression, schizophrenia and obesity.
