The genes included CADM2, BAG6, PHF2/FAM120AOS, NCAM1, CKAP2/TPTE2P3, and DOCK9. Four of the six loci are highly implicated in anxiety/mood disorders and there was a strong genome-wide genetic correlation of IBS with anxiety, neuroticism, depression, insomnia, and schizophrenia. This evidence concerns the gene CADM2 and mood disorder.
