Who has the highest chances of getting psoriatic arthritis?

ANSWER

About 10% to 30% of people with psoriasis get psoriatic arthritis. It can start at any age, but usually affects people between the ages of 30 and 50. While the cause is not known, genetic factors, along with the immune system, likely play a role.

As many as 40% of people with psoriatic arthritis have a family history of skin or joint disease. Having a parent with psoriasis triples the chance of getting psoriasis yourself. That raises your odds of psoriatic arthritis.
