SLC39A8 and schizophrenia: Recently, Li et al. performed a GWAS and meta-analysis of Chinese samples (7699 schizophrenia cases and 18,327 controls, called the Bio-X sample) and the PGC2 samples (35,476 schizophrenia cases and 46,839 controls, called the PGC2 sample), and no SNPs in the SLC39A8 locus was found to be associated with schizophrenia genome-wide significantly (p < 5E-8) [11].
