Using an regression algorithm, we identified a panel of 11 IgM autoantiboides including BPI, Fibrinogen IV, Hemocyanin, Histone H2B, Histone H3, Matrigel, Prothrombin protein, Sm, SmD, TPO and Vimentin, which can efficiently distinguish between sarcoidosis and healthy controls. This evidence concerns the gene CD40LG and sarcoidosis.
