What's this test for?

This test is ideal if you're experiencing skin findings like multiple café-au-lait spots, soft bumps under the skin, or a family history of Neurofibromatosis Type 1. It's also useful if you or a relative have been diagnosed with tumors linked to NF1, such as neurofibromas or pheochromocytoma, and want to understand the genetic cause. Many people use this test to help clarify a diagnosis or to check their own risk before starting a family.

What's included in this test?

This test looks at the entire NF1 gene using sequencing plus deletion/duplication analysis, which together catch both small spelling changes and larger missing or extra pieces of the gene. This dual approach matters because NF1 mutations can be very different from person to person, so relying on just one method could miss a mutation that the other method would catch.

What happens after I get my results?

Your results will appear in your secure online account, with a clear explanation of what a positive or negative finding means for the NF1 gene. If a pathogenic variant is found, next steps typically involve increased monitoring for related tumors and sharing the result with blood relatives who may also want testing. You can download a standard lab report directly from your account at any time, and since this is a one-time genetic result, tracking over time isn't usually needed, though you can keep the report saved in your trends history for reference.

How can I naturally support nerve and skin health?

While diet and lifestyle can't change your genes, some habits can support overall nerve and skin health if you carry an NF1 variant. Eating a balanced diet with antioxidants (found in berries, leafy greens, and nuts) supports skin repair, and staying hydrated helps skin stay resilient. Gentle sun protection can also help since skin changes are common with NF1. Regular physical activity supports nerve and muscle function generally, though it won't prevent NF1-related growths.

When will I get my results?

Results for this test are typically ready within about 7 days of your sample being received at the lab. Genetic tests like this one take a bit longer than routine blood work because the lab performs detailed sequencing and analysis of the entire NF1 gene. 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 physical signs of NF1, like multiple café-au-lait spots or skin neurofibromas, and for close relatives of someone already diagnosed with NF1. It's also worth considering if you're planning a family and want to know your chances of passing on the condition. Adults with a personal or family history of related tumors, like pheochromocytoma or peripheral nerve sheath tumors, may also benefit.

What symptoms indicate I may need this test?

Common signs include six or more café-au-lait (light brown) skin spots, soft or pea-sized bumps under or on the skin, freckling in the armpits or groin, and small growths in the colored part of the eye. Family history of NF1 or related tumors is also a strong reason to consider testing. Some people are prompted to test after being diagnosed with a nerve sheath tumor or pheochromocytoma.

What does a positive NF1 result mean?

A positive result means a pathogenic change was found in your NF1 gene, which explains an increased lifetime risk for neurofibromas (benign nerve tumors), certain nerve sheath cancers, pheochromocytoma (an adrenal gland tumor), and breast cancer in women. It doesn't tell you exactly which health issues will happen or when, since NF1 affects people very differently. This information can guide more frequent skin checks, imaging, or screening going forward.

What causes an NF1 gene mutation?

About half of NF1 cases are inherited from a parent who also carries the mutation, while the other half happen as a new, random change that starts with that individual. There's no specific lifestyle or environmental cause — it's simply a change in the genetic code that occurs during egg, sperm, or early embryo formation. Once present, the mutation can be passed on to future children with a 50% chance per pregnancy.

What should I do if my results are abnormal?

If a pathogenic NF1 variant is found, a reasonable next step is scheduling regular skin and physical exams to catch new neurofibromas early, along with periodic blood pressure checks to screen for pheochromocytoma. Sharing your result with close biological relatives lets them decide if they want testing too, since NF1 runs in families. If you notice a fast-growing lump, ongoing pain, or unusual symptoms, seek medical care promptly since this can signal a change in an existing growth.
