In our previous study [22], we performed a comprehensive analysis of plasma autoantibodies in patients with glaucoma using wet protein arrays (WPA) [23,24,25,26] and found that antibodies against ethanolamine kinase 1 (ETNK1), vimentin-type intermediate filament-associated coiled-coil protein (VMAC), nexilin (NEXN), and Sad1 and UNC84 Domain-Containing 1 (SUN1) are glaucoma-associated autoantibodies. Here, SUN1 is linked to glaucoma.
