The Genetics of Schizophrenia

The Genetics of Schizophrenia
Reported by
Karla Harby

Posted January 12, 2010

Overview

Schizophrenia is a neurological disease whose etiology is unknown. Some researchers believe that the human genome project may have a great impact on our understanding of such mental disorders because the genes scientists discover will provide crucial information about the mechanisms of these diseases. The results of genetic inquiries into complex diseases, particularly schizophrenia, were the subject of discussion at a June 7, 2006, session of the Academy's Genomic Medicine Discussion Group.

Topics discussed include the relationship between variations in the sequence of the genome and the risk of disease; discoveries to date in some complex genetic diseases, including stroke, heart attack, type 2 diabetes, and prostate cancer; and several molecular pathways that have been implicated in schizophrenia.

deCODE Genetics
Based in Reykjavik, Iceland, deCODE is a biopharmaceutical company applying its discoveries in human genetics to the development of drugs for common diseases. The company's population approach and resources have enabled its scientists to isolate key genes contributing to major public health challenges, from cardiovascular disease to cancer.

One of the National Institutes of Health, the mission of the NIMH is to reduce the burden of mental illness and behavioral disorders through research on mind, brain, and behavior. Included in the NIMH is the Clinical Brain Disorders Branch. Information for the public is provided at the Web site, including general information on schizophrenia, and on the NIMH Genetic Study of Schizophrenia.
