Genome-wide significant associations with BD and schizophrenia were detected for three previously reported loci, notably the 5’ region of ANK3 (rs10994359), CACNA1C (rs4765913 and rs4765905), and the chr3p21.3 locus (rs736408 and rs2239547), suggesting they are shared risk factors between BD and schizophrenia. The gene discussed is CACNA1C; the disease is schizophrenia.
