Genomic toxicology has several applications, including the identification of biomarkers for exposure and effect, which can be used for monitoring environmental and occupational exposures. It also plays a role in drug development, where it helps in understanding drug-induced toxicities, thus aiding in safer drug design. Furthermore, genomic toxicology is essential in personalized medicine, as it allows for the tailoring of therapeutic interventions based on individual genetic susceptibility to toxicants.
