Abstract An attractive hypothesis is that in utero exposure of hematopoietic cells to oncogenic agents can induce molecular changes leading to overt acute lymphoblastic leukemia (ALL) in infants and perhaps older children as well. Although supported by studies of identical infant twins with concordant leukemia, and of nontwined patients withMLL gene rearrangements, this concept has not been extended to the larger population of B-lineage ALL patients who lack unique nonconstitutive mutations or abnormally rearranged genes. We therefore sought to demonstrate a prenatal origin for 7 cases of B-cell precursor ALL (either CD10+ or CD10−) that had been diagnosed in infants and children 14 days to 9 years of age. Using a polymerase chain reaction–based assay, we identified the same clonotypic immunoglobulin heavy-chain complementarity determining region or T-cell receptor VD2-DD3 sequences in the neonatal blood spots (Guthrie card) and leukemic cell DNAs of 2 infants with CD10− ALL and 2 of the 5 older patients with CD10+ ALL. Nucleotide sequencing showed a paucity of N or P regions and shortened D germ line and conserved J sequences, indicative of cells arising from fetal hematopoiesis. Our findings strongly suggest a prenatal origin for some cases of B-cell precursor ALL lacking specific clonotypic abnormalities.
