In this study, we applied the same microanalytical method, using an extended array of 136 antigens (16 single and 120 heteromeric glycolipid complexes) to evaluate IgM and IgG antibodies in 42 CIAP patients, 32 GN patients, and 79 healthy controls in an attempt to shed light on the role of autoimmunity in these conditions. This evidence concerns the gene CD40LG and Autoimmunity.
