Exostosin, arkana laboratories, autoimmune diseases, renal pathology

Answer: D

Exostosin is an antigen that was recently identified out of a cohort of Phospholipase A2 Receptor (PLA2R) and Thrombospondin Type-1 Domain-Containing 7A (THSD7A) negative cases of Membranous GN. Results showed that EXT1/2 positive cases were associated with autoimmune disease, including systemic lupus erythematosus (see reference).
