摘要: This article reviews recent genome-wide association studies (GWAS) of schizophrenia and considers future research directions. Until recently, scans for disease risk variants were based on linkage analysis, an approach that can detect only those alleles confer relatively large effects. The main alternative was the candidate gene study, which, although better powered than weak genetic effects, is problematic phenotypes where pathogenesis largely unknown. However, systematic searches across genome small effect are now possible thanks to development array platforms allowing hundreds thousands single-nucleotide polymorphisms (SNPs) be assayed, genotypes which strongly correlated though disequilibrium with a high proportion 10 million or so common SNPs in human genome. Such GWAS have identified loci at variation confers susceptibility many diseases other polygenic traits, 1,2 this will increase as more larger samples studied.
