While previous research has linked genetic factors to the cause of Attention Deficit Hyperactivity Disorder (ADHD), there is yet to be conclusive evidence to identify the specific genes that can cause the neurodevelopmental disorder.

However, a new study out of Denmark is getting closer to identifying these specific genes and why ADHD can develop in some and not others.

The study, published in the peer-reviewed journal Nature Genetics in January, analyzed data on more than six million genetic variants in 38,691 people with ADHD and 186,843 people without the disorder. The researchers were able to identify 27 variations in the human DNA code that were most present in people with ADHD; however, they estimate there could be as many as 7,300 of these genetic variants.

The study also indicated genes linked to ADHD often have a high level of gene expression in brain tissues during the brain development stage as early on as the embryonic stage, which is between the fifth and 10th week of pregnancy.
