TLC immunostaining was recently used for detection of aPL (CL, antilysobisphosphatidic acid, and antiphosphatidylethanolamine antibodies) in a group of 36 patients with a clinical picture suggestive of APS, that is, vascular thrombosis and/or pregnancy morbidity associated with several noncriteria APS features (e.g., livedo reticularis, thrombocytopenia, cognitive dysfunctions, migraine, and seizures), persistently negative for the routinely used aPL [101]. Here, FASLG is linked to autoimmune polyendocrinopathy.
