rs6584400 is a SNP in the neuregulin 3 NRG3 gene.
Based on a study of 1515 Ashkenazi Jewish individuals, including 285 parent-child trios, 173 unrelated cases, and 487 unrelated controls, three SNPs (rs10883866, rs10748842, and rs6584400) were found to be associated with the "delusion" factor as a quantitative trait in schizophrenia, even though no SNP in this study withstood multiple test correction for association with the binary schizophrenia phenotype itself. After replication in an independent set of 153 Ashkenazi Jewish samples, the empirical study-wide significance across all 9 factors studied was estimated to be p = 2.7x10e-3.[PMID 19118813
