In this study, we aimed to characterize serum sCD23, BAFF, IgG, IgM, IgA, and kappa (κ) and lambda (λ) FLC in women with atopic asthma, to assess their variations during late pregnancy and the postpartum period and to compare these variations between healthy pregnant and nonpregnant women. The gene discussed is CD79A; the disease is atopic asthma.
