The GST-CSF2 protein was also recognized by serum IgG antibodies from patients with AIS (#007303, #07344, and #07684), TIA (#02291, #07278, and #07642), DM (#22297, #22370, and #22375), EC (#EC-3, #EC-4, and #EC-6), and CRC (#Co-3, #Co-5, and #Co-12), but not by the sera of the HDs (#09101, #07547, and #07572; Supplementary Figure S2). Here, CSF2 is linked to androgen insensitivity syndrome.
