Cancer Risk DNA Sequencers Get FDA Fast-Track Classification
Published Date: 10/6/2026
Rule
Summary
The FDA is officially putting high throughput DNA tests for hereditary cancer risk into a safer, easier-to-access category called Class II. This change means these tests will have special rules to keep them safe and effective, while also making it simpler for patients to get these life-saving tools. The new classification took effect on October 6, 2026, helping speed up innovation without extra costs for companies or patients.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Class II Reclassification Expands Access
The FDA has classified high throughput DNA sequencing tests for hereditary cancer predisposition as Class II (special controls). This classification is effective October 6, 2026 (and was applicable September 29, 2023) and the FDA says it will provide reasonable assurance of safety and effectiveness while enhancing patients' access by reducing regulatory burdens.
Required Accuracy and Validation Standards
Manufacturers must meet detailed validation and performance requirements, including minimum specimen testing counts and accuracy thresholds: for BRCA1 and BRCA2 at least 120 variant-positive specimens; at least 40 variant-positive specimens for other high-clinical-significance genes; overall accuracy must be >=99.0% for substitutions and insertions/deletions, CNV positive agreement >=99.0%, and CNV negative agreement >=99.9%.
Mandatory Patient and Provider Labeling Details
Labeling must include intended specimen types and validated mutation types, the testing facility name, a plain summary of how the test works and how to interpret results, performance summaries, and many limiting statements (for example: that the test is not for stand-alone diagnosis or prenatal testing, that a negative result does not rule out unidentified variants, and that physicians may consult a clinical medical geneticist or genetic counselor).
Prescription Requirement and Use Limits
These hereditary cancer sequencing tests are for prescription use only and are not intended for screening, prenatal testing, or as a stand-alone diagnostic test. The rule explicitly limits use to aiding hereditary cancer predisposition assessment by qualified health care professionals.
