A new study expands our understanding of the genetic basis of atteion-deficit/hyperactivity disorder (ADHD).
According to RCO News Agency, Groundbreaking research has discovered a combination of just three genes that can increase the risk of developing atteion deficit/hyperactivity disorder (ADHD) by up to 15 times.
According to New Atlas, an iernational group of scieists led by researchers from Aarhus University have shown that three rare varias in the genes MAP1A, ANO8 and ANK2 play a role in ADHD, a condition that is largely genetic and highly heritable.
Professor Anders Børglum (Anders Børglum), the senior author of the study from the Departme of Biomedicine at Aarhus University, says: “We can now for the first time poi to very specific genes in which rare varias create a high susceptibility to ADHD. The ideified varias are likely to have a very disruptive effect on the genes and show us exactly which genes and fundameal biological mechanisms may be affected.
The team analyzed genetic data from nearly 9,000 Danes with ADHD and 54,000 people without the condition, and compared it with data on brain cell function and reports on the education and socioeconomic status of Danish resides. People with these gene mutations tend to have, on average, lower academic achieveme and poorer socioeconomic status, which is often seen in people with ADHD.
Although rare, these mutations appear to disrupt communication between neurons by affecting the genes expressed in these very importa nerve cells in the brain. This ierference is one of the hallmarks of ADHD. These species especially affect the function of neurons that play a key role in regulating atteion, impulse corol and motivation.
Ditte Demois, a professor at the Departme of Biomedicine at Aarhus University and one of the co-authors of this article, said: Our findings confirm that disorders in the developme and functioning of the brain play a fundameal role in the developme of ADHD. We have also analyzed which proteins ieract with the proteins encoded by these three ideified genes and ideified a larger protein network that is also involved in other neurodevelopmeal disorders, including autism and schizophrenia. This provides insight io the biological correlates of several psychiatric diagnoses.
Importaly, these new findings enhance our understanding of the genetic makeup of ADHD; something that curre assessme protocols do not take io accou. Currely, the United States has no specific diagnostic tool, and doctors instead collect data through medical examinations, ierviews, family and personal history, school records, and informal rating scales. Genetic markers that are prese even before birth can help individuals, pares, and health care professionals with risk awareness, diagnosis, and treatme.
“This study provides a clear new direction for mapping the biological mechanisms involved in ADHD, as we now know the causative genes with the effector varias,” says Professor Borglum. They give us insight io some fundameal biological processes that can guide the design of deeper mechanistic studies, for example, to ideify new therapeutic targets.
The researchers add that these findings are by no means complete, and that more genes have yet to be discovered that may play a small or, as with these rare mutations, a large role in neural divergence.
This is the latest research to provide clues to the genetic nature of ADHD.
