Laboratory tests: Lower hemoglobin and hematocrit; higher RDW (14.8% vs. 13.4%, p < 0.001); more pronounced coagulopathy (prolonged PT and elevated INR, both p < 0.01); lower albumin (33.2 vs. 38.9 g/L, p < 0.001); and higher C-reactive protein. The gene discussed is CRP; the disease is blood coagulation disease.
