Blood DNA methylation profiles from schizophrenia cases, first episode psychosis patients and controls II

Genome-wide patterns of DNA methylation were quantified using the Illumina Infinium HumanMethylation450K BeadChip (“450K array”) in DNA samples isolated from blood for schizophrenia cases, first episode psychosis patients and controls. These samples were profiled as part of a wider study where they were meta-analysed with other cohorts. This data includes 800 adult samples profiled as part of a psychosis case control study design. Specifically it includes data for 290 schizophrenia cases, 307 first episode psychosis patients and 203 controls. All samples were recruited as part of IoPPN studies.
