Since the aβ2GPI IgA and aDI IgG frequencies were similar in the thrombotic APS and aPL (+) SLE groups and the aCL IgA frequency was low in both, logistic regression analysis showed that none of these noncriteria antibodies make any contribution to GAPSS in thrombotic risk prediction. The gene discussed is CD79A; the disease is systemic lupus erythematosus.
