Interestingly, rs1344706 is not the only SNP showing large differences in associations with schizophrenia between Han Chinese and Europeans, and similar situations were also observed for some other GWAS-identified SNPs in Europeans including NRGN rs12807809, RELN rs7341475, and CNNM2 rs7914558 [6], [7], [26], all of which were reported to be not significant in Chinese [25], [27], [28]. This evidence concerns the gene CNNM2 and schizophrenia.
