When twin sisters, Elizabeth and Kathryn Girtler, from Minnesota turned three years old, the doctors diagnosed them with a rare genetic disorder - congenital amegakaryocytic thrombocytopenia.
This disease is dangerous because it dramatically reduces the activity of bone marrow, which makes it incapable of producing blood platelets.
To survive, the girls needed an urgent bone marrow transplant, but finding a donor was almost impossible.
