Study Supports the Existence of Depression Gene

As reported by WebMD, a new study indicates that those with a depression gene may respond to stress different than those without the gene.

The meta study, which was published in the January 2011 issue of the Archives of General Psychiatry, said that those with a short variation of the serotonin transporter gene, also known as 5-HTTLPR, are more likely to become depressed when faced with stress. These findings were the result of analyzing 54 depression studies published between 2000 and 2010 that involve more than 41,000 participants.

However, despite the finding, researchers do not recommend gene testing because the gene’s effect on depression risk is still unknown.

However, scientists are hopeful that this study will prompt more research into how depression affects the brain and, ultimately, more effective treatments for depression.
