In addition to the level of anti‐AHNAK1 antibodies, the positivity rate for serum anti‐AHNAK1 antibodies was significantly greater in SLE compared to NHCs and the other control groups as well (Table 1) when the cutoff value for a positive reaction was designed as the mean OD of NHCs plus two SDs. The gene discussed is AHNAK; the disease is systemic lupus erythematosus.
