Of note, IL-17A and RAGE of the blue pattern displayed the most robust signals, consistently associated with the same pattern in separate analyses for each individual disease (Fig. 3C,D red pattern for the psoriasis trial, Supplementary Fig. 5A,B green pattern for the ankylosing spondylitis and C-D blue pattern for psoriatic arthritis trial). This evidence concerns the gene IL17A and psoriatic arthritis.
