Can Neonatal Diabetes Be Prevented or Cured? Neonatal diabetes is caused by a genetic mutation. There’s currently no way to prevent or cure it, but it can be managed. [nationwidechildrens.org]
Mutations in KCNJ11 that cause iDEND act by reducing the ability of cellular ATP to block to the KATP channel.[1,2,7] As a consequence, the channel remains open when blood glucose levels rise, preventing insulin secretion.[2] As the mutation (His46Leu [medscape.com]
