Blood DNA methylation profiles from first episode psychosis patients and controls I

Genome-wide patterns of DNA methylation were quantified using the Illumina Infinium HumanMethylationEPIC BeadChip (“EPIC 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 934 adult samples profiled as part of a psychosis case control study design. Specifically it includes data for 458 first-episode psychosis (FEP) cases and 558 controls recruited as part of the EU-GEI study.
