The time line for this discovery has been relatively fast. In July 2014, Broad researchers published the results of the largest genomic study on the disorder and found more than 100 genetic locations linked to schizophrenia. Based on that research, Harvard geneticist Steven McCarroll analyzed data from some 29,000 schizophrenia cases, 36,000 controls and 700 postmortem brains. The information was drawn from dozens of studies performed in 22 countries, all of which contribute to the worldwide database called the Psychiatric Genome Consortium.
