How Can Genetic Variability Influence Susceptibility to Environmental Toxins?
Genetic variability can also affect how individuals respond to environmental toxins such as pesticides, heavy metals, and air pollutants. For instance, polymorphisms in genes encoding for [glutathione S-transferases](https://www.ncbi.nlm.nih.gov/) (GSTs) can influence the detoxification of reactive oxygen species generated by environmental toxins. Individuals with certain GST variants may be more susceptible to oxidative stress and related health issues.
