Summary
IBBIS launched the Sequence Biosecurity Risk Consortium (SBRC) to create standardized, science-based definitions of biological 'sequences of concern' (SOCs) in synthetic nucleic acids. The consortium addresses inconsistent screening practices across DNA/RNA synthesis providers by developing shared rubrics, validated test sets, and consensus standards. It provides a collaborative forum for disclosing and addressing screening vulnerabilities across industry, policy, and scientific stakeholders.
Key Points
- •SBRC creates consensus engineering standards for identifying sequences of concern (SOCs) in synthetic DNA/RNA to reduce inconsistent screening across providers.
- •Key ambiguities addressed include whether sequences with benign synthetic biology uses but pathogen origins (e.g., IRES/2A sequences) should be flagged.
- •Resources include a biosecurity flag rubric and thousands of labeled test sequences for validating and benchmarking screening tools.
- •Funded by Sentinel Bio via IGSC and IBBIS, the consortium brings together synthesis providers, policymakers, screening developers, and scientific experts.
- •SBRC also serves as a trusted vulnerability disclosure forum, already responding to screening vulnerabilities including one reported in Science.

SBRC launched to engineer standard definitions of sequences of concern
IBBIS was proud to launch the Sequence Biosecurity Risk Consortium (SBRC), a community advancing global engineering standards for identifying and managing biological sequences of concern, at the 2025 iGEM Responsibility Conference .
The consortium defines “sequences of concern” (SOCs) based on a scientific assessment of biosecurity risk from synthetic nucleic acids. Its consensus-based engineering standards ensure that industry screening systems are aligned on what should be flagged, while providing a trusted forum to share and address uncertainties and vulnerabilities.
Why sequence biosecurity standards?
Responsible synthesis providers already screen DNA and RNA orders to prevent misuse. However, it’s unclear how to translate screening guidance and policies such as export controls into sequence-level decisions. IBBIS has contributed to several papers on this challenge, and highlighted several specific questions in a recent preprint :
Should sequences that are unique to a regulated pathogen, but which have common benign uses in synthetic biology (such as IRES and 2A sequences) be flagged?
Should sequences from non-regulated organisms with strong homology to regulated toxins (such as heat-labile E. coli enterotoxins with significant homology to Cholera toxin) be flagged?
Should sequences from regulated organisms be flagged if those sequences are unique, but not known to be virulence factors?
Without clear standard definitions of SOCs, providers face uncertainty that can lead to inconsistent decisions, lost customers, or regulatory penalties.
The SBRC narrows this uncertainty by defining shared interpretations of low-risk and high-risk sequences, while flagging areas where scientific disagreement remains. This approach promotes both security and responsible innovation in synthetic biology.
As we developed the Common Mechanism, we had to make subjective decisions about how to translate risk and regulation into screening decisions. Those decisions should not be based on the opinions of individual software developers and synthesis companies, but should be coordinated across the global industry. Through the SBRC, we are collaboratively developing a shared, science-based understand
