New DNA hope on schizophrenia: Discovery of 100 genes could help to transform treatment for the condition

• About one in 100 people will develop schizophrenia but there have been no new types of drug treatments for 60 years 
• ‘Astonishing’ study has the potential to ‘speed up the development of badly needed new treatments’

More than 100 schizophrenia genes have been pinpointed in a ‘remarkable’ British-led study that could transform the treatment of the debilitating mental illness
