Indeed, although the majority of TNDM cases have an abnormality in chromosome 6q24 and the other most frequent causes of NDM are missense mutations in the pancreatic β-cell KATP channel genes KCNJ11 and ABCC8, and in the preproinsulin gene, NDM has been linked to numerous other genetic causes including point mutations in GCK, GLIS3, EIF2AK3, PDX1, PTF1A, SLC2A2, HNF1B or FOXP3[1], [2], [3]. The gene discussed is FOXP3; the disease is neonatal diabetes mellitus.
