There are 2 main groups of people, people that have coeliac disease and in those cases there is a gene linkages. I have coeliac disease because someone in my family has it, although no one has been diagonsed, we think it my mum's side of the family. Although both my mum and dad have alot of trouble with gluten and wheat, they are in the 2nd group of people - those are intolerant to gluten and wheat. Which is happening more and more. The are not officially diagonosed as coeliacs, but they cannot handle too much of anything that has gluten and wheat.

Because I have it, there is a strong case Matthew will have it too and his kids even if he doesn't. We haven't tested him yet as he isn't showing symptons but we have been advised to test him sooner rather than later anyway.

Does this help Rachel? Let me know if you have further questions.
