In neuropsychiatric systemic lupus erythematosus (SLE) and autoimmune encephalitis (AE), normal studies do not rule out disease, although CSF total protein, albumin quotient, and IgG index can be abnormal and aid in diagnosis (Stock et al., 2013; Blinder and Lewerenz, 2019). The gene discussed is ALB; the disease is autoimmune encephalitis.
