Abstract: A method of diagnosing systemic lupus erythematosus using an antigen protein that binds specifically to an SMYD3 autoantibody present in body fluid of a patient with systemic lupus erythematosus. The diagnostic method uses a non-invasive biological sample such as blood, and thus may diagnose systemic lupus erythematosus very conveniently without burdening the patient, unlike conventional methods. In addition, the method has high specificity and sensitivity, and thus may be effectively used for early diagnosis of systemic lupus erythematosus.
