MODY types?
2- glucokinase deficiency
others- delayed insulin response too gllucose
MODY description?
Autosomal dominant –> dysfunctional beta cells
MOD treatment?
sulfonylureas (increase intracellular Ca2+)
What does HLA status have to diabetes?
Human leukocyte antigen
- 95% 3 or 4
- 3 aB against beta cells (later onset)
- 4 aB against insulin
- 2 protective
TCF7L2 effect
homozygous –> doubles risk (T2DM)
FTO effect
Increased obesity risk; works by modulate methylation of RNA
EPO
increased risk for retinal complications
