Methods are disclosed for genetically counseling a person based on one or more polymorphisms in his or her genes that sensitize him or her to toxic agents. Methods are also disclosed for genetically screening a group of individuals and/or a human population, based on, for example, ethnicity, race, religion. or geographic region, to identify individuals with such polymorphisms for counseling. The methods can be used to counsel a person who has not been genetically tested for polymorphisms but who might have increased risk for sensitivity to toxic agents due to his or her membership in a particular group and/or population. The methods use correlations between genotypes of polymorphic alleles in a panel of cell lines and sensitivity of the cell lines to toxic agents. As examples, the methods are used to identify genotypes of allelic forms of the genes TP53, OGG1, ERCC2, XRCC1, and NOS3 that increase sensitivity or resistance of cells to toxic agents. |
