Laboratory tests revealed leukocyte count of 19,370 cells/mm3 with 77% neutrophils and 2% rods; hemoglobin 14 g/dL and hematocrit 40.4%; thrombocytopenia (platelets 29,000/mm3); acute renal failure (creatinine 2.92 U/dL, urea 153 U/dL); and elevated serum liver enzymes (AST 464 U/L and ALT 137 U/L) and creatine phosphokinase (CPK) (99 U/L). This evidence concerns the gene PIK3C2A and Thrombocytopenia.
