Table I. Published genome-wide association studies (GWASs) for schizophrenia.21-30,32 The number of variants investigated, the best associated single-nucleotide polymorphism(s)-SNP(s) - found and the gene(s) containing the SNP(s), the corresponding Pvalue(s), and the number of cases and controls in the discovery and the replication/meta-ana lysis sample are all given. Genome-wide significant findings are highlighted in bold EA, European Ancestry Individuals; AA, African-American Individuals; ND, no data available; NR, no replication .
