Is RA an inherited disease?

[Guest guest]

I know has probably posted several articles on this before, but my brain

fogs up. Has RA been proven to be genetic and passed down from parents to kids

or grandparents to grandkids? Neither of my parents have RA (but neither have

they been tested) but my paternal grandfather, grandmother and her siblings did.

I just found this out this past family reunion. My great uncle apparently had

'lockjaw' like I do from his RA. I'm just worried about my children who are 2

and 7. I didn't show RA signs until after the birth of my first, but I thought

I was just doing something wrong mechanically at work. Now I know it was

probably the first signs of RA.
