Genetic aspects of induced mutation.

F Vogel

    Human Genetics. Supplement
    |January 1, 1978
    PubMed
    Summary

    Genetic variability in humans and test animals can misclassify mutagenic agents. Considering individual differences in agent uptake, metabolism, and DNA action, and using in vitro testing on patient cells, can mitigate risks.

    Area of Science:

    • Toxicology
    • Genetics
    • Pharmacology

    Background:

    • Genetic variability within species can impact the accuracy of mutagenicity testing.
    • Differences in agent uptake, metabolism, and DNA interaction are key factors.
    • Current testing methods may not fully account for individual genetic differences.

    Purpose of the Study:

    • To highlight the impact of genetic variability on mutagenicity testing.
    • To propose a more personalized approach to assessing mutagenic risks.
    • To reduce misclassification of potentially hazardous agents.

    Main Methods:

    • Review of existing literature on genetic variability and mutagenicity.
    • Analysis of three critical levels: agent uptake, metabolism, and DNA action.
    • Proposal for in vitro testing using cells from individuals receiving the agent.

    Main Results:

    • Genetic variability can lead to misclassification of mutagenic agents.
    • Individual differences in pharmacokinetic and pharmacodynamic processes are significant.
    • In vitro testing on patient-derived cells offers a potential solution.

    Conclusions:

    • Accounting for genetic variability is crucial for accurate mutagenicity assessment.
    • Personalized in vitro testing strategies can improve hazard identification.
    • This approach can enhance the safety of chemical and drug administration.
