Conversely, anti-DFS70 antibodies were detected by CIA in 11/443 (2.5%) patients (9 women and 2 males; mean value, 118 CU; range, 23.9-450): two with APS, two with VTE, one with arterial thrombosis, five with RPL, one with thrombosis on treatment with heparin, and in 1/244 (0.4%) control with atrial fibrillation (43.8 CU) (p = 0.06) (Fig. 1). Here, PSIP1 is linked to autoimmune polyendocrinopathy.
