“nr-axSpA” = nonradiographic axial spondyloarthritis; “r-axSpA” = radiographic axial spondyloarthritis; ASAS = Assessment of SpondyloArthritis International Society; mNY diagnostic criteria = modified New York diagnostic criteria; “AS” = ankylosing spondylitis. mNY = modified New York, ASAS = Assessment of SpondyloArthritis International Society classification criteria; r-axSpA = radiographic axial spondyloarthritis; AS = ankylosing spondylitis. is to be noted that mNY are diagnostic criteria [10]. factors include HLA B27, ERAP-1, and IL23R and certain protein biomarkers include KIR3DL1, Sclerostin, and Dkk-1. of acute phase response is genetically determined, for example, C-reactive protein response.
