Schizophrenia (SCZ)

Workgroup Chairs: Michael O’Donovan and James Walters

SCZ Data Access Portal

The Schizophrenia workgroup has been a part of the PGC since 2007. During that time, our membership has grown to include over 400 investigators from more than 100 institutions representing 40 countries.

Professor Michael O’Donovan chairs our group. Our interdisciplinary membership includes graduate and postdoctoral trainees in psychiatric genetics as well as distinguished faculty with a wide range of expertise including human genetics, psychiatry, biostatistics, bioinformatics, psychology, cognitive neuroscience, cellular modelling and drug discovery. Working together we have studied the DNA of over 38,000 individuals with schizophrenia. This has allowed us to conduct very large genome-wide association studies (GWAS), which in turn has identified large numbers of common DNA variants associated with increased risk for schizophrenia (over 140), including unpublished data-PMID: 25056061, and PMID: 21926974). We have, with colleagues in the Copy Number Variant analysis group, conducted one of the largest analyses of rare copy number variation and identified novel loci that are associated with schizophrenia (PMID: 27869829). Our group has worked with the Cross-Disorder group to define the degree of genetic overlap between major psychiatric disorders (PMID: 23933821PMID: 23453885), we have also worked with the Network and Pathways analysis group to identify biological processes likely to mediate the impact of genetic variation on schizophrenia (PMID: 26007216) – including synaptic function, chromatin remodelling and immune processes.

Our current goals are to expand our samples to include at least 100,000 people with schizophrenia, and to enhance the ancestral diversity of those samples in order to capture more of the common and rare genetic variation that impact on risk of the disorder. This will allow us to carry out work aimed at further establishing the pathophysiological process underlying schizophrenia. These samples will be used to help develop algorithms aimed at predicting important clinical outcomes, for example, treatment resistance. We aim to stratify those with schizophrenia, potentially with the addition of those with other psychiatric disorders, into subgroups that may be relatively aetiologically homogeneous. From this, we may be able to identify patient strata who have different therapeutic needs.

Members of the workgroup stay connected through regular conference calls (the frequency of which depends on need), regular email contact on a list serve, and via a Google group.
