Candidate genes for schizophrenia were drawn from SZGene (Allen et al., 2008) (courtesy Dr. Lars Bertram on 11/09/2009). SZGene included studies evaluating associations between a genetic variant and schizophrenia and published in a peer-reviewed, English language journal (Allen et al., 2008). Studies were identified via PubMed, bibliographies, and tables of contents. To ensure that the list was not “contaminated” by the results of GWAS, SZGene entries from GWAS were removed as were genes studied only subsequent to identification in a GWAS. As only ISC autosomal results were available, 15 chromosome X genes were dropped. The list of autosomal hypothesis-driven candidate genes for schizophrenia contained 732 genes from 1,374 studies (Table S1).
