Gene Linked to Low IQ

Medical Xpress, March 25, 2014


Children with both a common gene variant and lower thyroid hormone levels, which occurs in approximately 4% of the population, are four times more likely to have a low IQ, according to research presented today by the University at the Society for Endocrinology annual BES conference.
It is well established that thyroid hormones are essential for brain development in childhood. More recently, scientists have looked at a certain enzyme, called deiodonase-2, involved in processing thyroid hormones inside cells. A variant in the gene coding this enzyme has already been associated with key health outcomes including diabetes and high blood pressure, although the precise mechanism remains unclear.
In this study, researchers from Cardiff and the University of Bristol examined the genetic data and thyroid function of 3,123 children aged 7 who also had their IQ tested, as part of the Avon Longitudinal Study of Parents and Children (ALSPAC). The researchers found that children with thyroid hormone levels in the lower part of the normal population range who also possessed this genetic variant were four times more likely to have an IQ under 85.
This result stood true after taking into account various differences in environmental and socio-economic factors such as social class. Children with lower thyroid hormone levels alone did not have an increased risk of lower IQ, highlighting that without genetic analysis the population at risk could not be identified.
The study’s results will need to be confirmed in other groups of children. “If other studies confirm our finding then there may be benefit in carrying out a genetic test for this gene variant in addition to the standard neonatal thyroid screening, which would identify children most at risk of developing low IQ,” said lead researcher Dr Peter Taylor, from the School of Medicine. {snip}

Soon, china will know every intelligence gene and create amazingly smart children: all of them will be geniuses: every Chinese will have twice the IQ of Einstein.

second to top: don't forget nature's chosen people.  

But China will make their intelligence higher and higher and higher forever, becoming gods, becoming the new chosen people.

chosen people: 110
Han: 105
Japan: 108
Korea: 108
White: 100
Black: 70
Hispanic: 89

This is based on IQ testing over many years.
