Laboratory workup revealed normocytic hemolytic anemia with an Hb level of 62 g/L, mean corpuscular volume (MCV) of 86 fL, elevated reticulocyte count of 9.3%, schistocytes count of 3% on the peripheral smear, thrombocytopenia (platelet count 23 × 109/L), a serum creatinine (SCr) level of 0.62 mg/dl, blood urea nitrogen (BUN) level of 5.66 mmol/L, cystine (C) level of 1.57 mg/L, C3 level of 0.89 g/L, C4 level of 0.21 g/L, a markedly increased lactate dehydrogenase (LDH) level of 585.1 U/L, hematuria (red blood cells 4,627.9/μl), and proteinuria (3+). Here, GSTM1 is linked to Thrombocytopenia.
