Noncriteria laboratory findings associated with APS include IgG or IgM aCL or anti-beta2-GPI levels in the range of 20 to 39 GPL or MPL units, IgA aCL and IgA anti-beta2-GPI, anti-phosphatidylserine and anti-phosphatidylethanolamine antibodies, anti-prothrombin antibodies, and antibodies to the phosphatidylserine-prothrombin complex. Here, CD40LG is linked to autoimmune polyendocrinopathy.
