Laboratory blood values indicated leukopenia (white blood cells 2.41 × 10∗9/L) and thrombocytopenia (platelets 69 × 10∗9/L), hypergammaglobulinemia (IgG 2720 mg/dL), hypocomplementemia (complement C3 66 mg/dL, C4 15.6 mg /dL), presence of autoantibodies such as anti-SSA, anti-Ro52 antibodies, an elevated antinuclear antibody titer of 1:100, and an elevated rheumatoid factor titer (1600 IU/mL). This evidence concerns the gene TRIM21 and Decreased total leukocyte count.
