NARSAD Grantees Involved in the Largest Schizophrenia Research Study to Date

Story highlights


Momentum is building in the largest experiment ever in schizophrenia research: 13 more regions in the human gene code, or genome, have been identified as being associated with schizophrenia in the most recent report from genome-wide association studies (GWAS). An international team led by NARSAD Distinguished Investigator Grantee, Patrick Sullivan, M.D., of the University of North Carolina, Chapel Hill, combined a large group of DNA samples from their Swedish collaborators with previous GWAS data, creating a study of more than 20,000 schizophrenia subjects and bringing the total of published genomic suspects linked to the disorder to more than 20.
More work will have to be done to drill down and figure out what the "hits" from this study represent. In their paper, published August 25th in the journal Nature Genetics, Dr. Sullivan and his co-authors highlight two of them: there seems to be good evidence for involvement of molecules that move the element calcium into cells and for a molecule that regulates the production of various proteins.
Although the new results represent progress, they are not the end goal, according to Dr. Sullivan. The number of genetic suspects that can be found in GWAS increases with the number of study subjects, and the international Psychiatric GWAS Consortium has gathered, but not yet published, genetic data (called genotypes) from more than 30,000 people. "We hope to genotype 100,000 people above and beyond what we have right now," said Dr. Sullivan.

Many other NARSAD Grantees contributed to this study.
