Congenital Amegakaryocytic Thrombocytopenia

What is congenital amegakaryocytic thrombocytopenia?

Congenital amegakaryocytic thrombocytopenia (CAT) is a severely low platelet count and clot-forming cell count. It is present at birth.

If your child is born with congenital amegakaryocytic thrombocytopenia, he may have early bleeding and bruising. As your child grows, he may develop a decrease in all blood cell lines and be at risk for leukemia.

CAT is diagnosed with a physical exam of your child, a family medical history, and blood and genetic tests.
