The P-values for the other cases were not significant (controls for CCL3L3, P = 0.8595; SLE cases for CCL3L3, P = 1.0; controls for CCL3L1, P = 1.0; SLE cases for CCL3L3, P = 1.0; controls for C4A, P = 0.9481; SLE cases for C4A, P = 0.9905; SLE cases for C4B, P = 0.8447). This evidence concerns the gene C4A and systemic lupus erythematosus.
