I had read the same hypothesis about the two (ERAP1 and IL23R). I'm glad you are encouraging others to do the tests as well as I honestly think there is something to this Axial (ERAP1) versus more Peripheral (IR23R) involvement and wonder about others AND, how it in massive results, it could help many seeking the proper care.

If this is something found with substance, it would certainly turn my life around as for 25 years I have been told all my issues have no bearing on AS (or SpA).
