In addition, rare MODY cases [accounting for up to 6% of all MODY forms (49)] have been diagnosed with mutations in PDX1 (59), HNF1B (60), NEUROD1 (61, 62), KLF11 (63), CEL (64), PAX4 (65), INS (66), BLK (67), ABCC8 (68), KCNJ11 (69), and APPL1 (70) (known as MODY4-14). The gene discussed is ABCC8; the disease is MODY.
