(The Conversation) – There could be a way of predicting – and preventing – which children will go on to have low intelligence, according to the findings of a study researchers at Cardiff University presented on Monday. They discovered that children with two copies of a common gene (Thr92Ala), together with low levels of thyroid hormone are four times more likely to have a low IQ. This combination occurs in about 4% of the UK population.
