Considerations for Using Genetic and Epigenetic Information in Occupational Health Risk Assessment and Standard...

Area of Science:

• Occupational Health
• Toxicology
• Genetics & Epigenetics

Background:

• Risk assessment is crucial for occupational health and setting exposure limits.
• Genetic and epigenetic factors influence biological responses to hazards and can be targets of them.
• Current risk assessment paradigms have not fully integrated genetic and epigenetic data.

Purpose of the Study:

• To explore the use of genetic and epigenetic information in occupational risk assessment.
• To provide guidance for integrating this data into existing risk assessment frameworks.
• To propose a structured approach for utilizing genetic and epigenetic data in standard setting.

Main Methods:

• Development of a 4x4 matrix framework.
• The matrix maps risk assessment functions against genetic and epigenetic data types.
• Identification of specific applications within each cell of the matrix.

Main Results:

• Genetic and epigenetic data can serve as endpoints for hazard identification.
• These data can act as exposure indicators and effect modifiers.
• Applications include describing modes of action and characterizing toxicity pathways.

Conclusions:

• Genetic and epigenetic data offer potential to reduce uncertainty in risk assessment extrapolations.
• High-throughput technologies generate vast datasets for variability assessment.
• This integration may lead to a new paradigm of toxicity pathway-based risk assessments.
