Whilst the aim of this study was not to find association with cases for this cohort, two PES were nominally associated with schizophrenia in the ASRB - Regulation of Insulin Secretion (z = 2.262, P = 0.0237) and the Acetylcholine Binding and Downstream Events pathways (z = 2.167, P = 0.0303). The gene discussed is INS; the disease is schizophrenia.
