Siblings and Type1

Have a younger brother with type 1 diagnosed at age 15-36 years ago. My diagnosis came at age 54-3 years ago. He has been a great support. Other brother diabetes free.
 
I was diagnosed at 20, 18 years ago with T1. My brother, now 36, enrolled on the diabetes TrailNet 3 years ago where they found 3 type 1 diabetes antibodies. He goes in every 6 six months when they do a whole load of tests on him. Fingers crossed no symptomatic signs of diabetes.....yet.
 
My sister is 36 and not diabetic. I have no family history of type 1 diabetes.

I would like to get my sister, and my nephew, signed up to trial net.

If you have a relative with type 1 you have a 15 times greater risk of type 1 than someone without a relative with type 1. But that is 15 time a really small risk, remains a really small risk.

You can get signed up for trial net antibody testing if you're aged 3-40 and have a brother, sister, parent or child with type 1 (so yes, the inherited risk factor goes up and down) or if you age 3-20 and have a cousin, uncle, aunt, nephew, niece, half-brother, half-sister or grandparent with type 1.

Been diagnosed 5 years now, was 16 at the time. My sister is 2 and 1/2 years younger, and so far nothing, thankfully. If there was anything I could do to make sure that she never gets it, I would do it in a heartbeat. I am hoping, on the basis that there is zero family history, and the fact that I was never really a well child whereas she has always been amazingly healthy, that it will get the hint and stay away from her. My mum's theory is that the trigger was the Swine Flu, which I had 3 years before diagnosis, but no-one else in my family did.
 
My dad and his brother with diagnosed within a week of each other when they were in their teens. Their sister never got T1D though. Interestingly they were part of a study for viral markers in their blood, my dad and uncle had the marker but their sister didn't, and she was away on holiday at the time of them becoming ill. Interesting I thought.

On the other hand I am T1 but my brother isnt.

 
51 years a Type 1. Identical twin brothers 20 months younger than myself and neither they or anyone else in the family have become Type 1 or 2.
 
Goes female, male, female (ending with me, so far) i our family.

However, my 2 older brothers are not diabetic.

My nan was T2 and her son, my uncle was LADA.

Hopefully as I have no children, it wont go to my nephew.. and I can be the last in our family.
