SLC39A8 and schizophrenia: Discovery of a SLC39A8 variant allele with schizophrenia was quickly followed up by a considerably larger GWAS of >36,900 cases and >113,000 controls; among 108 highly statistically significant loci identified, the above-described SLC39A8 (p.Ala391Thr) gene variant (P = 8.0 × 10−15) was found [61], thereby confirming the original 2010 study [60].
