Furthermore, anti-HSA IgG levels did not correlate with total-IgG levels, neither in SLE patients (r = −0.004034; p = 0.9571) nor in healthy controls (r = −0.04186; p = 0.5684) suggesting that the occurrence of anti-HSA IgG did not reflect polyclonal B-cell activation. The gene discussed is ALB; the disease is systemic lupus erythematosus.
