Familial autoimmunity. The vertical axis corresponds to the proband's disease and each disease individually. In the horizontal axis diseases present in first degree relatives are shown. Each color belongs to the proband's disease. The figure only includes significant results and may serve as a guide for clinical practice in order to search ADs in FDRs of probands. Note that familial autoimmune disease is excluded. AA, alopecia areata; AdD, Addison's disease; AS, ankylosing spondylitis; AITD, autoimmune thyroid disease; CD, celiac disease; CrD, Crohn's disease; FDR, first degree relative; IBD, inflammatory bowel disease; IIM, idiopathic inflammatory myositis; JDM, juvenile dermatomyositis; JRA, juvenile rheumatoid arthritis; JSLE, juvenile systemic lupus erythematosus; MAS, multiple autoimmune syndrome; MG, myasthenia gravis; MS, multiple sclerosis; PA, pernicious anemia; PAN, polyarteritis nodosa; PBC, primary biliary cirrhosis; PSO, psoriasis; RA, rheumatoid arthritis; SLE, systemic lupus erythematosus; SS, Sjögren's syndrome; SSc, systemic sclerosis; T1D, type 1 diabetes; UC, ulcerative colitis; VIT, vitiligo; WG, Wegener's granulomatosis. Note: Although AS is considered an auto inflammatory more than autoimmune disease  we show the results obtained.
