Fig. 1: Genetic correlations across 14 autoimmune diseases in European ancestry.

Left panel indicates genetic correlations across 14 autoimmune diseases. Genetic correlation is estimated using cross-trait LDSC. Color intensity and size of square are proportional to strength of genetic correlation (brown = negative correlation, green = positive correlation). Asterisks indicate genetic correlations that are statistically significant at false discovery rate level of 0.05. Red boxes highlight the correlation between SLE and other traits. Right panel illustrates the network of significantly genetically-correlated traits. The colors of the lines represent the magnitude of genetic correlation estimates using LDSC. The widths of the lines represent the statistical significance. Disease name abbreviations: ANā=āankylosing spondylitis, ATDā=āautoimmune thyroid disease, CDā=āCrohnās disease, CELā=āceliac disease, MSā=āmultiple sclerosis, PBCā=āprimary biliary cirrhosis, PSOAā=āpsoriatic arthritis, RAā=ārheumatoid arthritis, SJOā=āSjogrenās syndrome, SLEā=āsystemic lupus erythematosus, SSCā=āsystemic sclerosis, T1Dā=ātype 1 diabetes, UCā=āulcerative colitis, VITā=āvitiligo.
