What's this test for?

This test is ideal if you're experiencing recurring lung collapses, unusual skin bumps, or if kidney tumors and lung cysts run in your family. It's also useful if a relative has already been diagnosed with Birt-Hogg-Dube syndrome and you want to know if you carry the same gene change. Knowing your genetic status can help guide decisions about screening and monitoring before symptoms become serious.

What's included in this test?

This test looks at the FLCN gene using two methods: sequencing, which scans for small spelling changes in the gene's code, and deletion/duplication analysis, which checks for larger missing or extra chunks of the gene. Using both methods together gives a more complete picture, since some gene changes are only detectable by one method or the other.

What happens after I get my results?

Your results will be available in your account, with an explanation of what a positive or negative finding means for the FLCN gene. If a pathogenic variant is found, next steps typically include starting regular kidney imaging and lung checks to catch any changes early, since BHD-related risks are manageable with monitoring. You can download the full lab report from your account at any time, and if you test other family members later, you can track results over time using the trends feature.

How can I naturally support kidney and lung health?
While genetics can't be changed, you can support your kidneys and lungs with simple habits like staying hydrated, avoiding smoking, and keeping blood pressure in a healthy range. Regular exercise and a balanced diet low in processed foods also help reduce extra strain on these organs. If you have a family history of BHD, pairing these habits with routine imaging checks gives you the best chance of catching issues early.
When will I get my results?
Results for this genetic test are typically ready within about 7 days after your sample is received at the lab. Because this involves detailed gene analysis, it takes a bit longer than a standard blood test. You'll get a notification as soon as your results are posted to your account.
Who should consider this test?
This test is a good fit for people with a family history of Birt-Hogg-Dube syndrome, kidney tumors, or repeated spontaneous lung collapses. It's also worth considering if you have multiple skin growths on your face, neck, or upper body that started in adulthood. Anyone with a first-degree relative who already tested positive for an FLCN variant should strongly consider testing as well.
What symptoms indicate I may need this test?
Common signs linked to BHD syndrome include small, dome-shaped skin bumps (usually on the face, neck, or chest), sudden chest pain or shortness of breath from a collapsed lung, and a personal or family history of kidney tumors. Multiple lung cysts found on a chest scan can also be a clue. If you notice several of these together, especially with a family history, this test can help clarify whether BHD is the cause.
What is Birt-Hogg-Dube syndrome and why does it matter?
Birt-Hogg-Dube (BHD) syndrome is an inherited condition caused by changes in the FLCN gene that raises the risk of skin growths, lung cysts, sudden lung collapses, and kidney tumors. It matters because early knowledge of your genetic status allows you to start regular kidney and lung monitoring before problems become severe. Since it's inherited, a diagnosis can also prompt testing for other family members who may be at risk.
What does a positive result mean?
A positive result means a pathogenic variant was found in your FLCN gene, which is consistent with a diagnosis of BHD syndrome. This doesn't mean you already have kidney tumors or lung problems, but it does mean your lifetime risk is elevated, so regular imaging and monitoring become important. It also means close relatives may want to get tested, since BHD is passed down through families.
What should I do if my results are positive?
If your result is positive, the most important next step is setting up regular kidney imaging (like an ultrasound or MRI) and monitoring for lung and skin changes, since catching issues early makes them easier to manage. It's also a good idea to share the result with close biological relatives, since they may carry the same gene change. Keeping a symptom log of any new skin bumps or breathing changes can help you track things between screenings.

FLCN Gene Variant Negative
Demo results
Negative (No Variant Found) Positive (Pathogenic Variant Found)
Negative

What this means

A negative result means no pathogenic change was found in the FLCN gene using sequencing or deletion/duplication analysis. This lowers the likelihood of Birt-Hogg-Dube syndrome, especially if a specific variant was already known in your family.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
