Iron studies and the remainder of the anemia workup were normal except for elevated lactic dehydrogenase (LDH) at 449 U/L (normal range 135–225 g/dL for males), erythrocyte sedimentation rate (ESR) 36 mm/hr (normal range males >50 years is ≤ 20 mm/hr) and C-reactive protein (CRP) at 8.7 mg/dL (normal range <3 mg/dL) Notably, the PT/INR remained subtherapeutic at 1.6 (previously 6.2 a week before admission). The gene discussed is CRP; the disease is anemia (phenotype).
