The effects of ionizing radiation on single nucleotide polymorphism (SNP) copy number variations between TK6 and WTK1 cell lines are described herein. Specifically, the integrity of the chromosomes for two WIL2-derived lymphoblastoid cell lines (TK6 and WTK1) was analyzed in the presence and absence of ionizing radiation. WTK1 cells contain a p53 mutation, whereas the TK6 cell line has the native p53 tumor-suppressor gene. Each cell line was isolated post-irradiation for SNP analysis, which showed significant, genome-wide impacts on both cell lines; for the mutant WTK1 sample, there were a total of 48 gene deletions and no gene amplifications, whereas for the wild-type TK6 sample, there were 217 gene deletions and 9 gene amplifications. It appears that both cell lines are affected in the areas of cell-cycle control, but that other affected areas differ significantly between the two.
