  'Gene map for depression' sparks hopes of new generation of treatments.

  Scientists have raised hopes for more effective treatments for depression, a condition that affects over 300 million people globally, after mapping out the genetic foundations of the mental disorder in unprecedented detail.

  In the world’s largest investigation into the impact of DNA on the mental disorder, more than 200 researchers identified 44 gene variants that raise the risk of depression. Of those, 30 have never been connected to the condition before.

  By tripling the number of gene regions linked to depression, scientists now hope to understand more about why the disorder strikes some but not others, even when they have similar life experiences. The work could also help in the search for drugs to treat the condition which affects as many as one in four people over a lifetime.
