I’m not a scientist. Heck! I don’t even play one on TV. But I most definitely can attest to the fact that almost all aspects of mental illness can be found to have some genetic component to them. When a child is born with ADHD, we would be hard-pressed to find that there is not some type of mental health issues effecting one or both of the child’s biological parents that attributed to the ADHD in the child.
So, it is no surprise that the more studies that are done with genetics, the more we are finding things like the newest information regarding genetics and eating disorders. We already know that the tendency for eating disorders has been found to run in families, however, we have not been able to identify the specific genes directly related to putting people at greater risks because of their familial connection.
At least not up until now. Two groups of scientists, one from the University of Iowa and the other from the University of Texas Southwestern Medical Center, have been researching two families that have been very negatively impacted by eating disorders, because of two totally different gene mutations.
What makes these finding unique, is that although the two families are not connected and the two gene mutations are totally different, there is interaction in the same signaling pathway in the brain that produce the same effect biologically.
Let me back up for a moment. About one in every thousand women will die from anorexia. With that fact as the stimulus for these scientists, the study which can be found in the Journal of Clinical Investigation, published October 8, 2013, the mutations that decrease activity in a protein in the brain that turns on expression of other genes, increases the risk of eating disorders.
Again, I’m no scientist, but to me this means that when our brains don’t get enough of a certain type of activity due to some type of defect, it causes an increased in the chances of there being eating disorders.
Large families have to be studied in order to get strong statistics to conclusively back up the differences. The genetics have to indicate what people with the disorder have in common that people without the disorder don’t have.
This study permitted researchers to work with two families, one with 20 members from three generations and one with eight members. Half the individuals in the first family were affected by the disorder and six of the eight in the second family were affected. The results led to the identification of two new genes now associated with eating disorders and more research to come that might help lead the way in working with people who suffer with them.
Although the combinations are pretty much endless, when there is a hit; when two genes like these show similar results, it really makes tremendous progress in learning more about and treating the problems.
Now that is productive research!
