A) Mass spectrometry data from 279 MN cases are shown and are grouped together based on immunostaining results. The abundances of the indicated proteins are plotted as Z-scores. Abundances of the index biomarker proteins are relatively low in MN cases of known antigen type (PLA2R+, THSD7A+, EXT+, NELL1+), and abundances of canonical antigens are low in the index cases. Peptides of the known antigen types are highlighted with an increased size within the dot plots.
B) Protein abundance of FCN3 in index case and controls.
C) Protein abundance of CD206 in index case and controls.
