We found that OCR SNPs on Chromosome 6 were not only in strong LD with schizophrenia and bipolar disorder GWAS index SNPs, but also with the most significant eQTL for three transcripts of the BTN2A1, ZSCAN12P1, and H4C13 genes (r2 with the top eQTL of between .88 and 1) in fetal brain. The gene discussed is BTN2A1; the disease is bipolar disorder.
