MODY inheritence
Autosomal dominant
Becker inheritence
X-linked recessive
Most common form of MODY?
HNF1 alpha
HNF1 MODY?
Most common form, lowers the amount of insulin made by the pacnreas
Onset, treatment and complications of glucokinase MODY?
Onset at birth
Stable hyperglycaemia
Diet treatment
Complications rare
Onset, treatment and complications of transcription factor mutation MODY? (e.g. HNF1 alpha)
Adolescence/young adult onset
Progressive hyperglycaemia1/3 diet, 1/3 OHA, 1/3 Insulin
Complications frequent
Treatment proven to work really well in HNF1 alpha MODY?
Gliclazide
Treatment for neontatal diabetes?
Requires insulin treatment within first 3 months of life
remember you have transient and permanent neonatal diabetes though
Transient neonatal diabetes
Diabetes usually diagnosed < 1 week
Resolves median 12 weeks
Stop insulin
Permanent neonatal diabetes
Diabetes usually diagnosed 0 - 6 weeks
Lifelong treatment with insulin
This type of drug binds to the KATP channel in the pancreatic beta cell?
Sulphonylurea
stops hyperpolarisation = cell becomes depolarised = calcium enters = insulin released
Mutations in Kir6.2 associated with what?
Associated with PNDM (permanent neonatal diabetes)
Neonatal diabetes can be caused by mutations in which channel?
Potassium channel mutations
