摘要

Epidemiological evidence has suggested that some pediatric leukemias may be initiated in utero and, for some pairs of identical twins with concordant leukemia, this possibility has been strongly endorsed by molecular studies of clonality. Direct evidence for a prenatal origin can only be derived by prospective or retrospective detection of leukemia-specific mo- lecular abnormalities in fetal or newborn samples. We report a PCR-based method that has been developed to scrutinize neo- natal blood spots (Guthrie cards) for the presence of numerically infrequent leukemic cells at birth in individuals who subse- quently developed leukemia.
