Study links genetic causes that can lead to eating disorders
A group of American researchers have detected specific genes that could increase the risk of suffering from certain eating disorders such as nervous anorexia and bulimia.
“There are two genetic mutations that appear to be associated with an increased risk of developing this type of disorder,” say members of the research team from the University of Iowa and the Southwestern Medical Center at the University of Texas .
The study shows that genes interact in the same direction of signaling in the brain and the two mutations end up triggering the same biological effect.
To detect this phenomenon, the researchers analyzed large families in which at least one member suffers from an eating disorder.
Eating disorders and their cultural factors
The results suggest that this research opens up a field of analysis to try to understand more deeply the disorders associated with eating, and although in many cases the influence of culture and the ideals of beauty of advertising play a decisive role, the field of research on the influence of certain genes in the development of such pathologies can clarify new unknowns and open new avenues towards a better diagnosis and a better understanding of diseases.
The study also suggests that the mutations responsible for reducing the activity of estrogen receptor alpha protein, The function is to mobilize the expression of other genes, to increase the risk of undergoing these alterations.
