Pharmacogenomics

Pharmacogenomics, powered by clinical genomics.

Our own 67-locus panel, our own analysis engine and a clinical report covering more than 270 drugs across 23 clinical areas. For the right drug, the right dose, the right treatment.

Our pharmacogenomic reports are clinical decision support and do not replace the physician’s judgement.

A genomic view of pharmacogenomics.

Most pharmacogenomic tests look at a few predefined positions and report whatever they find there. We look with the eyes of a genomics laboratory: we read the coding region of the gene, call the known alleles and assess the rest with experience from interpreting more than 3,000 exomes.

Position-targeted genotyping

Only preselected positions are read. A variant in between stays invisible.

not read

BIODECODE targeted sequencing and genomic interpretation

Coding regions are sequenced end to end. Known alleles are called, and an unexpected variant is also caught and reported separately with its evidence.

rare missense variant detected with ACMG criteria, gnomAD frequency, REVEL and AlphaMissense scores
  • Star-allele defining position
  • Sequenced coding region
  • Non-star-allele variant
  • Clinical genomics experience

    The variant-interpretation expertise built across more than 3,000 patients’ exome analyses is applied to pharmacogenes with the same rigour.

  • Evidence-based caution

    Non-star-allele findings never change the phenotype; they are presented in a separate section with ACMG codes and population frequency. A computational score alone never produces a “pathogenic” verdict.

  • Integrity from one hand

    The same team designs the panel, analyses the data and writes the report. Nothing gets lost in hand-offs.

We treat pharmacogenomics not as a genotyping service, but as a genome analysis problem.
The BIODECODE approach

BIODECODE among global platforms.

The world’s pharmacogenomic platforms fall into two families: targeted SNP panels and NGS panels. BIODECODE is engineered to lead both on every axis that changes a prescription.

The differenceA platform that reads the whole gene, interprets findings functionally and generates the report automatically. Very few players worldwide offer all three together.

Structural variants and copy-number changes are assessed with limited resolution on short-read data; CYP2D6 is measured by depth ratio and confirmatory testing is recommended when needed. The comparison reflects typical characteristics of platform families; individual products may differ.

67 loci, six classes, one sequencing run.

A targeted capture panel of our own design, manufactured on Twist Bioscience technology. Tap a gene to see its class, the terms used for it in the report, and the key drugs it is linked to in guidelines.

Associated drugs are established examples from CPIC or DPWG guidelines or FDA labelling, not a complete list. All 270+ drugs appear in the report on drug cards with their evidence levels.

From sample to verdict, a traceable pipeline.

Internationally standard tools and our own modules run in the same pipeline. Every step is documented gene by gene in the report’s methods section.

  1. Targeted next-generation sequencing

    Peripheral blood, 67-locus panel

    Libraries are prepared from genomic DNA with our panel and sequenced on next-generation platforms.

  2. Alignment and quality

    BWA-MEM, GATK, GRCh38

    Reads are aligned to the current reference genome; duplicates are marked and base qualities recalibrated.

  3. Variant calling and annotation

    Funcotator, gnomAD, ACMG criteria score

    Every variant is annotated with population frequency and ACMG criteria.

  4. Star-allele calling

    BIODECODE PGx engine, PharmVar definitions

    Diplotypes are determined from PharmVar allele definitions; phenotypes are assigned from CPIC tables.

  5. CYP2D6 and HLA modules

    Read-based phasing, OptiType multi-solution

    Genes for which standard matching is unreliable on short reads are called by our own modules and passed to the engine as external calls.

  6. Loss-of-function screening

    REVEL, AlphaMissense, ACMG

    Non-star-allele missense variants are scored and reported separately with their evidence levels.

  7. Guideline verdict

    CPIC, DPWG, FDA

    The verdict comes from a single, version-controlled knowledge base. Where authorities disagree, the difference is shown in the report.

The hardest gene, the most transparent result.

CYP2D6 affects a large share of prescribed drugs and is the hardest pharmacogene to call from short reads. Instead of hiding uncertainty, we measure and report it.

  • Most likely diplotype and alternative scenarioWhen phase cannot be resolved, the candidate made of common alleles is chosen, and the rare candidate is shown separately rather than discarded.
  • Drugs whose verdict would change are listedDrugs whose decision would change under the alternative scenario are listed one by one and flagged on their cards.
  • Copy-number and alignment checksCopy-number deviation is checked by depth ratio, and CYP2D7 -derived alignment noise is filtered by allele fraction.

Report page

We wrote our quality down as promises.

These are not preferences but rules every report must meet. A report that breaks one does not go into clinical use.

  • No call does not mean “normal”.

    For every gene without a star-allele call, we state what was done and what was found: screening result, measured depth, panel coverage. We never produce results by assumption.

  • Colour never carries meaning alone.

    Every action is shown with a symbol ✕ ▲ ◆ ● and a label. The report says the same thing when printed in black and white.

  • The verdict comes from a single source.

    Even our custom modules’ calls are passed to the engine; the guideline verdict always comes from CPIC, DPWG and FDA tables. A discrepancy is never silently fixed; it becomes a visible warning.

  • No numeric dose is ever invented.

    Every dose statement in the report comes from a version-controlled source table, together with its source text. The clinical decision belongs to the physician, based on the whole patient.

One result, three different readers.

Physicians, patients and institutions look at the same genotype with different questions.

A report read drug by drug, not gene by gene.

The report is organised by clinical area; each drug card shows the verdict, source gene, authority and full guideline text together. Drugs with the same verdict are grouped on one card.

Terminology follows the gene class: metabolizer for enzymes, function for transporters, risk allele for HLA. CYP3A5 and similar genes, where the CPIC term can mislead, use “Expresser”.

Prodrug warning
For prodrugs such as codeine, tramadol and clopidogrel, the reversed direction of metabolism is explained explicitly.
HLA
A risk allele is shown with its corresponding drugs in the report; an allele not seen in every typing solution is not called positive.
Confirmation advice
At the limits of short-read data (copy number, hybrid alleles), a confirmatory method is explicitly recommended.
