Comparable results were obtained by Koning J.P. et al. (2011), who did not reveal statistically significant associations between rs1800497 (TaqI_A) (C/T), rs6277 (C957T) (T/C), rs1800498 (TaqI_D) (T/C), and rs1799732 (−141C) (C/Del) of the DRD2 gene and the risk of developing AIP in patients with schizophrenia. The gene discussed is DRD2; the disease is autoimmune pancreatitis.
