My paternal grandmother was T2, and 2 of my aunts were diagnosed T2, but the one who's still alive at 83, is sure that she's a T1 or T1.5, and when I heard her history, I agree. Trouble was 40 years ago, if you were 40+. you had to be T2. She had the thirst, peeiing etc, and is now on MDI with no complications. I think my other aunt may also have been T1.5, but I can't prove it. No-one on Mum's side of the family. The haemochromatosis also comes from Dad's family - same aunt has it, her son has it, another cousin has it. And there's coeliac, too. My cousin, who is the son of my other diabetic aunt, has it. And my bother has MS, All auto immune conditions.
Jelli, I was always told that T1 was a recessive gene, but ...
Infundo ergo sum.
