Is there a duty to routinely reinterpret genomic variant classifications?

Area of Science:

• Genomic Medicine
• Clinical Genetics
• Bioethics

Background:

• Periodic reanalysis of genomic test results increases diagnostic yield.
• Routine reanalysis for all patients is currently infeasible.
• Reinterpreting previously classified variants is a sustainable alternative.

Purpose of the Study:

• To examine the ethical considerations of a duty to reinterpret genomic variant classifications.
• To assess the implications of reinterpretation outcomes (upgrades, downgrades, regrades).
• To determine if diagnostic laboratories should routinely reissue reports for materially relevant variant classification changes.

Main Methods:

• Analysis of ethical obligations regarding genomic variant reinterpretation.
• Assessment of reinterpretation outcomes in the context of duties of care, error risks, and diagnostic equity.
• Ethical and practical evaluation of a potential duty to reinterpret.

Main Results:

• A general duty to reinterpret all genomic variant classifications is not supported.
• A restricted duty to reinterpret is ethically justifiable and necessary for responsible genomics implementation.
• Reinterpretation must consider duties of care, systemic errors, and diagnostic equity.

Conclusions:

• Responsible implementation of clinical genomics requires a carefully defined duty to reinterpret variant classifications.
• This duty balances the benefits of updated genetic information with practical limitations.
• Ongoing ethical and systemic considerations are crucial for genomic healthcare.
