Tetraphocomelia in the syndrome of thrombocytopenia with absent radii (TAR syndrome).Am J Med Genet. 1985 Apr; 20(4):571-6.AJ
We report on an infant with the syndrome of Thrombocytopenia with Absent Radii (TAR) with severe lower-limb involvement. Amegakaryocytic thrombocytopenia was detected at 6 days when the platelet count was 11,000/microL. The platelet count increased steadily to 100,000/microL at 3 years. The patient required bilateral above-knee amputations for femorotibial synostoses. We recommend postponement of all elective operations until platelet counts are normal.
