This draft report is a description of an approach to evaluate genomic data for use in risk assessment and a case study to illustrate the approach. The dibutyl phthalate (DBP) case study example focuses on male reproductive developmental effects and the qualitative application of the available genomic data. The case study presented in this draft document is a separate activity from any of the ongoing IRIS human health assessments for the phthalates.
This draft report describes an approach to evaluating toxicogenomic data for use in risk assessment and a case study of DBP. A multi-disciplinary team of scientists developed the approach for utilizing genomic data in risk assessment and performed the DBP case study. The principles of the approach include examining the genomic and toxicity data sets together, defining a set of questions to direct the evaluation, and performing new analyses of genomic data, when relevant. The draft includes the development of exploratory methods and preliminary results from genomic data analyses. In addition, recommendations, research needs, and potential future directions were identified. The approach and document may serve as a template for evaluating and analyzing genomic data in future chemical assessments and by researchers performing genomic studies.
