On the basis of recent data from candidate region/gene and genome-wide association studies (GWAS) and their follow-up investigations, the number of genes potentially implicated in schizophrenia has been estimated to be over 1000. However, with regard to the identified odds ratio, it is likely that genetic variants with more definitive effect on schizophrenia phenotype are still missing. The hunt therefore remains open for the genetic variants that would explain the majority of the missing heritability of schizophrenia. This review aims at summarizing data from recent DNA microarray and target gene/region resequencing in order to propose new insights of where to look next. The review is divided into three sections: GWAS, copy-number variations and rare variant--candidate gene resequencing.
