Article’s main point: Researchers have discovered why people with Trisomy 21 (Down syndrome) have a higher risk of developing a type of leukemia known as acute megakaryoblastic leukemia (AMKL).
Answer: Trisomy 21 is linked to leukemia due to the presence of an extra copy of a gene called GATA1, which leads to the overproduction of megakaryocytes and an increased risk of AMKL.
