Professionals debate whether to screen whole-genome sequencing data for all mutations or focus on precision medicine. This review examines the ethics of searching for and disclosing incidental findings.
Area of Science:
- Genomics
- Bioethics
Background:
- Whole-genome sequencing (WGS) generates vast amounts of data.
- Current practices vary regarding the extent of WGS data analysis.
Purpose of the Study:
- To ethically review the systematic screening of WGS data for incidental mutations.
- To compare the implications of actively searching versus incidentally discovering mutations.
Main Methods:
- Ethical analysis of arguments for and against comprehensive WGS data screening.
- Comparison of the ethical considerations for proactive mutation searching versus incidental disclosure.
Main Results:
- The debate centers on balancing potential benefits of broad screening against risks and resource implications.
- Incidental findings raise distinct ethical issues concerning patient autonomy and the duty to inform.
Conclusions:
- Systematic WGS data screening for all mutations presents significant ethical challenges.
- Precision medicine approaches, focusing on the primary indication for testing, are often favored, but ethical frameworks for incidental findings require careful consideration.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
