-- Verified 99.8% Concordance Rate Through Collaborative Study with Tohoku University --
TOKYO--(BUSINESS WIRE)--Mitate Zepto Technica (MZT, headquartered in Shibuya, Tokyo; CEO: Keisuke Harashima) announced today that its genome analysis-specific accelerator prototype, “RASEN,” has achieved precision equivalent to conventional methods. In a joint study with Tohoku University, RASEN demonstrated a 99.8% concordance rate compared to the widely used BWA tool, achieving a balance of speed and accuracy never before realized.
Summary of Verification Results
High Concordance:
• Achieved an average concordance rate of 99.8% across all 12 samples.
• Several samples showed a perfect 100% match.
Consistent Precision:
• Maintained a concordance rate above 99.6% across all samples.
• No bias observed related to ethnicity or gender.
Reliable Mapping Accuracy:
• Discrepancies were minimal and consistent across samples.
• High reliability was confirmed through detailed visual inspections.
Future Outlook
The RASEN prototype has already been validated to complete whole-genome sequencing within five minutes, as confirmed by MZT’s internal speed tests. These results showcase the feasibility of realizing a final product using advanced semiconductor technology.
Building on this success, MZT will accelerate the development of its semiconductor-integrated final product. The newly developed semiconductor will significantly enhance processing speed and energy efficiency.
RASEN aims to become a vital infrastructure for next-generation genome analysis, addressing the growing need for rapid, large-scale genomic data processing in clinical and research settings. By enabling researchers and medical institutions to quickly utilize data, it will contribute to advancements in personalized medicine and early detection of genetic disorders.
MZT will strengthen collaborations with domestic and international partners to incorporate real-world feedback, driving continuous improvement and optimization of the product.
Through RASEN, MZT is committed to addressing a wide range of needs from research to clinical applications, paving the way for groundbreaking innovations in genomics, medicine, and biotechnology.
