Schizophrenia is a severe mental disorder affecting ~1% of the world population, with heritability of up to 80%. To identify new common genetic risk factors, we performed a genome-wide association study (GWAS) in the Han Chinese population. The discovery sample set consisted of 3,750 patients and 6,468 healthy controls (1,578 cases and 1,592 controls from the Northern Han; 1,238 cases and 2,856 controls from the Central Han; 934 cases and 2,020 controls from the Southern Han); and we followed up the top association signals in an additional independent cohort of 4,383 cases and 4,539 controls from the Han Chinese. Meta-analysis identified genome-wide significant association of common SNPs with schizophrenia on chromosome 8p12 (rs16887244, P=1.27×10−10) and 1q24.2 (rs10489202, P=9.50×10−9). Our findings provide new insights into the pathogenesis of schizophrenia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
