title: Advances in the genetics of spondyloarthritis and clinical implications.
abstract: Spondyloarthritis (SpA) is a group of inflammatory rheumatic diseases whose main clinical feature is inflammation of the axial spine. Articular, periarticular, and extra-articular manifestations can also occur, depending on the type of spondyloarthritis. The most common clinical subsets of SpA are ankylosing spondylitis (AS) and psoriatic arthritis (PsA). SpA is a major health challenge given the propensity to affect young adults and the potential requirement for lifelong treatment. Although the precise etiology of SpA is unknown, there is mounting evidence that these diseases are a result of complex interplay of genetic, environmental, and immunological factors. In this review on SpA, we will discuss genetic variants with genome-wide significance, highlight potential clinical application of genetic variants, and discuss challenges in further elucidating the genetic basis of SpA.
