| Research Abstract |
Genomic mutations and their transmission were analyzed using SNP array and microsatellite markers in the DNAS derived from peripheral blood cells before and after radiation and chemotherapy in 26 survivors of childhood cancer. In all cases, aberrations of SNP or copy numbers were detected between 21 and 2,745 markers (mean: 476). Microsatellite mutations were detected in 2 cases. The same analyses in the DNAs of children and partners in these cases, transmission of genomic mutation were confirmed in 3 cases and microsatellite mutations were detected in one of these 3 cases. These mutations were significantly correlated with usage of anthracycline agents and radiation therapy. All these survivors were female. These data suggested that genomic mutations derived from childhood cancer therapy transmit to the next generation.
