Covering a wider spectrum of rare diseases to help patients

Despite sharing symptoms, many rare disease patients have different etiology. Coupled with an extremely narrow disease spectrum within genetic testing, this leads to low diagnostic rates.

3billion’s genetic testing process seeks to improve efficiency across the board. By covering 20,000+ genes, we can detect 7,000+ currently-known rare genetic diseases.

List of diseases related to 25 phenotype categories. Each category has average of 1200 related diseases.

Free reanalysis

for undiagnosed patients

3billion provides full-cycle reanalysis until the patient is successfully diagnosed, at no additional cost.

~10% of undiagnosed patients receive diagnosis via reanalyses. With ~20 rare disease-gene associations discovered each month, 75% of newly-diagnosed patients end their diagnostic odyssey via these new associations. (Machini K et al., 2019, Costain G et al., 2018).

Improved Diagnostic Rates via Automated Variant Interpretation

3billion process schematic from patient visit to diagnosis

100,000+ genetic variants found across 20,000+ genes must be interpreted for each patient. This process takes medical geneticists anywhere from 6½ to 8½ hours, per patient (Machini K et al., 2019). Due to complexity of variant interpretation, genetic testing is both expensive and often inconsistent.

Here at 3billion, we’ve devised a solution—a variant interpretation system deemed EVIDENCE—to automate this process. By utilizing cutting-edge technology, variant interpretation with EVIDENCE takes an average of less than 5 minutes, per patient.

EVIDENCE produces consistent variant interpretation which aligns with current medical and ACMG-AMP interpretation guidelines.

3billion’s medical geneticist has gone on to confirm reported variants by Sanger validation (Richards S et al., 2015).

We've collaborated with 120+ medical institutions across 40+ countries

Since 2018, 3billion has collaborated with 120+ medical institutions and corporations around the world, spanning 40+ countries, all of us with the common goal of ending the diagnostic odyssey.

In initial collaborative studies, causative variants were found in 65.1% of patients, while 42.7% of patients were diagnosed during a follow-up assessment with their physician(s) (Seo GH et al., 2020).
