Heterozygous GCK mutations may manifest as mild hyperglycemia, which is not progressive, and usually requires no treatment. Homozygous GCK mutations result in permanent neonatal diabetes. MODY, type 2 maturity-onset diabetes of the young (disease) caused by mutation in GCK maturity-onset diabetes of the young
