What about genes?

[jiml]

I've put none because as far as I know non of my grandparents on mother's or father's side suffered with it,although my grandfather on my mother's side is an unsure as he cleared off when my mum was a toddler . My mother and father certainly didn't have it, I had  3 sisters non of them had it to my knowledge, they all had children that are now adult with children of their own and non show signs of psoriasis or psoriatic arthritis . Both my children now in their mid 40s and their children now teen-agers show any sign of it
So I'm the odd ball in the family,and glad it hasn't reared its head in my offspring
