Register now: criteria for cases
The National Psoriasis BioBank is currently collecting DNA from two groups of people: those who have psoriasis and/or psoriatic arthritis (cases), and those who do not (controls).
Case participants (those with psoriasis and/or psoriatic arthritis) must:
- Be age 15 or older
- Be the only person in their immediate family participating in the BioBank ("immediate family" is defined as grandparents, parents, siblings, children and grandchildren)
- Have a dermatologist and/or rheumatologist who can verify their diagnosis
- Have not given blood or tissue sample to another psoriasis-related study
- Have no personal history of several other inflammatory disorders, including: eczema, atopic dermatitis, and cutaneous T-cell lymphoma
