70 Patients Found New Answers Through Reanalysis of Genetic Testing: March 2026

Is a single genetic test result the end of the diagnostic journey?
At 3billion, we believe diagnosis is an ongoing process. That’s why we focus not only on the test itself, but on what comes after:
Reanalysis.

For all cases previously reported as Inconclusive or Negative,
3billion performs automated reanalysis through a continuous system.
Each month, dozens of reports are updated, revealing new diagnostic insights and possibilities.

Summary of Diagnostic Changes This Month

In March 2026, a total of 70 patients received updated reports through reanalysis. 

Why did the results change?

---

• 43%: Variant database updates
• 25%: Disease database updates
• 19%:  Algorithm improvement
• 10%: Additional clinical or phenotype data
• 3%: Segregation analysis

📍This means that as clinical and scientific data evolve, the same patient data can lead to a different diagnosis over time.

Let’s take a look at a real-world case where reanalysis led to a new result through a variant database update.

💡  The Power of Reanalysis: A Real Case

In February 2026, two variants were identified in a patient’s genetic test. The first variant was confirmed as Pathogenic (P), but the second variant (NM_001282225.2:c.140G>A) was classified as a Variant of Uncertain Significance (VUS). Since both variants needed to be pathogenic for a diagnosis to be made, the initial report was issued as Inconclusive.

About ten days later, this variant was newly submitted to ClinVar — a global genetic variant database — and classified as LP (Likely Pathogenic).

3billion’s reanalysis system automatically detected this update and reclassified the variant from VUS to LP. As a result, the patient’s report was reissued as Positive.

As this case illustrates, a reanalysis system is essential for keeping pace with constantly evolving databases. 3billion automates this process to deliver results faster and at a more accessible cost.

So, how exactly does automated reanalysis work?

It continuously monitors the latest variant and disease databases, updates internal interpretation models, and incorporates new phenotype and family history data submitted by clinicians.

Diagnosis doesn’t end with a single report.

It continues as the knowledge base grows— and 3billion’s automated reanalysis system ensures patients benefit from that progress.
