What does it mean when Genome Explorer says a variant is Pathogenic?
By Dr. Brandon Colby, MD, Founder of Sequencing and author of Outsmart Your Genes. An early voice in direct-to-consumer genetic testing.
Genome Explorer is a tool for viewing raw DNA data and public annotations. When a variant is labeled Pathogenic, that label refers to how the variant itself is classified in scientific sources. It is not a medical diagnosis and it does not by itself indicate your personal risk.
Why Genome Explorer shows terms like Pathogenic and Benign
- These are standard genetics terms used in clinical and research databases such as ClinVar.
- Pathogenic means there is evidence that the variant can contribute to disease.
- Benign means the variant is not currently thought to cause disease.
- The label is tied to the variant record, not to any single person.
Important context about your own DNA
- A variant can display as Pathogenic even if you do not carry that variant. Check the Your Data or Genotype column to confirm whether it appears in your genome.
- Even if you do carry a variant labeled Pathogenic, actual health impact depends on many factors such as zygosity, other variants, clinical history, and environment. A label alone does not predict disease.
How to get interpretation that applies to you
- Use Sequencing apps that provide interpreted results for your genome. These apps connect your actual genotype to relevant clinical context and summarize next steps.
- If results raise health questions, consider discussing them with a qualified clinician or genetic counselor.
Where classifications come from
- Genome Explorer displays labels sourced from public variant databases and literature curation.
- Classifications can change over time as new evidence becomes available. Revisit your results periodically to see updates.
Frequently Asked Questions
No. It indicates that the variant can be associated with disease in some contexts. It is not a prediction for an individual.
Explorer shows the classification for the variant record. Use the Your Data or Genotype column to confirm whether that variant is present in your genome.
Not always. Risk depends on factors such as zygosity, penetrance, gene interactions, age, and clinical context.
Run an interpretation app designed for health insights, then review the app result for your specific genotype. For medical decisions, consult a clinician or genetic counselor.
Yes. Variant classifications are updated as new research is published. Explorer will reflect updates when source databases change.
