Figure S2. Pairwise LD patterns of four IFNL3/4 locus SNPs on chromosome 19 show coefficient of linkage disequilibrium D′ (red) and square of correlation coefficient between two indicator variables γ2 (black) of all subjects (A), SLE cases (B), and healthy controls (C), respectively. Here, IFNL3 is linked to systemic lupus erythematosus.
