Genetic detection causes children to have low IQ

Scientists have found that one gene increases the risk of children being less intelligent.

The research team at Cardiff and Bristol University (UK) analyzed 3,123 genetic data for children under 7 years of age and was tested for IQ.

As a result, the scientists found that children with low levels of thyroid hormones and mutated deiodonase-2 genes had low IQ (less than 85 points), four times higher than children. for high levels of thyroid learning and no deiodonase-2 gene.

The gene deiodonase-2 is important when it is involved in controlling levels of thyroid hormones in the body's cells . This genetic change is also thought to be related to other health problems, including diabetes and high blood pressure.

The scientists also found that children with low thyroid hormone levels and the normal deiodonase-2 gene were also less likely to be less intelligent. New findings mean genetic testing after birth can detect early risk babies with low IQ and seek treatment.

Dr. Peter Taylor, of Cardiff University, said: 'If other studies confirm our findings, the method of genetic testing combined with thyroid tomography will be able to identify children with risk of low IQ or not '.

About 4% of children born each year are genetically modified deiodonase-2 and low thyroid hormone. Giving your child a thyroid hormone supplement can help their brain and IQ grow normally. This can help 30,000 children avoid the risk of being less intelligent each year.
