Research shows that genes are less likely to cause mental disorders

A study from The Bioscience Resource Project shows that the cause of common conditions such as attention deficit hyperactivity disorder, autism and major depressive disorder may not be genetic.

Researchers found that repeated the failure of a new and comprehensive genome scanning method to find important human disease genes may indicate that some common disorder are not inherited.

Furthermore, they said that of the approximately 1,000 genes identified that note an increased risk of developing these conditions, most have relatively little influence. The remaining genes have little significance to human health.

The study argues that these diseases are determined by diet and non-genetic factors. Officials said that the new findings show that genetic research strongly supports environmental explanations of disease.

Furthermore, this research refutes the notion that genes have hiding places for which diseases are located, but have yet to be discovered.

Officials suggested that research needs to shift toward the broader environmental and dietary causes of these disorders.
