The exact cause of Crohn's is unknown, but genetic factors are thought to play a role. Up to 5% of those with the disease have one or more affected relatives. It is two to three times more common in those with jewish ancestry, but a pattern of Mendelian inheritance has not been identified.

There is a strong tendency to run in families, but it is not a pure genetic disease. The genes make you susceptible, but environmental factors also apply. There is an association with tumor necrosis factor (TNF) from the immune system, but it is far from proven.

My mom has it too... But noone else in my family has been diagnosed w/ it.. I'm thinking it may be from her father's side of the family. I also wonder if I might get it. I hope not. I see what she has gone through and I pray I don't get it... It's kinda odd. I don't understand how it's genetic since that something that can't be diagnosed 'til later...

I am wondering the same thing because My grandfather has it, my mom's 2nd brother has it and she also has it I am wondering if I am going to get it because the 3 of them have had it for 22 years if not longer. I am wondering why its genetic because of the fact that they didnt know they had it until later.
