New Research Suggests Many Distinct Psychiatric Diseases Share a Common Genetic Structure

Several distinct psychiatric diseases share a common genetic structure, in accordance with new research by scientists at Massachusetts General Hospital (MGH) and the Psychiatric Genomics Consortium, an international group of investigators. Psychiatric disorders have an effect on more than 25 % of the population in a given year. Within the largest-ever research of its type, published within the journal Cell, researchers recognized more than 100 genetic variants that have an effect on the risk for multiple mental health conditions.

A gene is made up of segments of DNA; an alteration within the DNA sequence produces a gene variant, which might increase or lower the risk for disease. Many particular person gene variants that have an effect on the risk for specific psychiatric disorders have been recognized. Nonetheless, genes are sometimes pleiotropic, which means they produce a number of effects within the body.

Figuring out gene variants that affect the chance for multiple psychiatric disorder is an important step towards bettering the diagnosis and treatment of those situations, says the study’s senior author, Jordan W. Smoller, MD, ScD, director of MGH’s Psychiatric and Neurodevelopmental Genetics Unit and a professor of psychiatry at Harvard Medical School (HMS).

To determine these multi-purpose gene variants, the researchers used a technique known as a genome-wide association to investigate genetic information from 494,162 healthy control topics and 232,964 individuals diagnosed with at the least certainly one of eight common psychiatric disorders.

Moreover, the research identified a number of gene variants that had especially widespread influence on the danger for numerous psychiatric disorders, which might prove to be an important finding for the prevention and care of psychiatric disorders.
