However, meta-analysis of the Japanese samples with 479 cases and 2938 controls from a United Kingdom (UK) schizophrenia GWAS showed that the SULT6B1 SNP (p = 3.7 × 10−5) as well as SNPs in the GIRK2 (rs2787566, p = 0.0014) and NOTCH4 (rs2071287, p = 0.0014) genes were associated with schizophrenia. Here, KCNJ6 is linked to schizophrenia.
