| Research Abstract |
The human genome (the complete set of genetic information in people's DNA) somewhat differs among individuals, and such variation is in part responsible for how individuals differ in their susceptibility to radiation-related DNA damage and diseases. We detected radiation-related DNA damage in blood cells of A-bomb survivors and investigated associations between frequencies of DNA-damaged cells and genotypes of DNA repair genes. Our results suggest that the difference in the genotype of P53BP1 may be involved in the individual's difference in the frequency of GPA mutant blood cells.
