The first two years of life are the most critical in TAR syndrome. During this time, children frequently develop life-threatening bleeding episodes due to extremely low platelet levels (thrombocytopenia). These episodes decrease with age, and platelet counts are usually normal by the time a child goes to school. Many individuals with TAR syndrome are allergic to cow's milk, which can also exacerbate the symptoms of thrombocytopenia. Intellectual development is usually not affected by TAR syndrome, though some individuals have intellectual disability due to complications from bleeding within the brain. People with TAR syndrome may be at increased risk of developing acute leukemia during childhood or adulthood.
