A previous analysis of de novo CNVs by WGS in individuals suffering from bipolar disorder and schizophrenia showed that a microdeletion that affects TAOK3 (and PEBP1) is present in schizophrenia patient (Malhotra et al., 2011) and TAOK3 (but not PEBP1) was further confirmed in a GWAS analysis (Gilman et al., 2012), suggesting that TAOK3 alone may contribute to NDDs, at least in schizophrenia. Here, PEBP1 is linked to bipolar disorder.
