Identification of preleukemic precursors of hyperdiploid acute lymphoblastic leukemia in cord blood

Abstract excerpt

Previous studies involving identical twins with concordant leukemia and retrospective scrutiny of archived neonatal blood spots have shown that common chromosome translocations of pediatric leukemia frequently arise before birth. The IGH/TCR clonotypic sequences used as surrogate molecular markers suggest this is also likely to be true for hyperdiploid acute lymphoblastic leukemia (ALL). Yet evidence that...
