Laboratory evaluation showed elevation of the erythrocyte sedimentation rate (ESR) 140 mm/first hour and C-reactive protein (CRP) 7.75 mg/dL, normocytic and normochromic anemia (Hb 10.1 g/dL), and increased serum creatinine (3.96 mg/dL) and urea (103 mg/dL). This evidence concerns the gene GSTM1 and anemia.
