Congenital Amegakaryocytic Thrombocytopenia
Also known as: CAT, CAMT
What is congenital amegakaryocytic thrombocytopenia?
Megakaryocytes are formed in the bone marrow from an early stem cell, and they, through a complex process produce platelets which play a very important role in blood clotting and the prevention of bleeding. CAT is a rare disorder (two types) found in infants where there are very few megakaryocytes and platelets in bone marrow
, and while initially the bone marrow produces red and white cells this eventually decreases /stops so the baby/child has a lack of platelets, red cells and white cells. Children with CAT may be at risk for other bone marrow diseases.
What causes congenital amegakaryocytic thrombocytopenia?
CAT is an inherited congenital disorder (babies are born with it) caused by mutations (changes) in a specific gene.
What are the signs/ symptoms of congenital amegakaryocytic thrombocytopenia?
Children with CAT tend to bruise easily, can experience life-threatening bleeding or have tiny red dots under the skin from bleeding (called petechiae). They may also have abnormalities of brain function, heart problems and other malformations.
What are congenital amegakaryocytic thrombocytopenia care options?
Children with CAT frequently need blood transfusions. A stem cell transplant can cure the disease in some patients..

At a young age, Bi’Yanie was diagnosed with sickle cell, a blood disorder that causes the cells to take on a crescent or sickle shape and can lead to very painful episodes called crises. Today, Bi’Yanie is getting stronger by the day, thanks to the bone marrow transplant she received at Nicklaus Children’s Hospital.
