Li-Fraumeni syndrome

Li-Fraumeni syndrome can have a genetic cause, and genetic testing may help identify whether one is involved.

Also known as: Also known as: LFS, LFS1, LFS3, SBLA syndrome, Li Fraumeni syndrome, TP53 Li-Fraumeni syndrome, TP53-related Li-Fraumeni syndrome, sarcoma family syndrome of Li and Fraumeni

Because the symptoms of many conditions overlap, a single genetic test looks across a broad set of genes at once, so you do not have to test for one condition at a time.

FAQ

Frequently asked questions

How do I know if my child's symptoms have a genetic cause?

Many genetic conditions look like ordinary pediatric symptoms at first. If your child has symptoms without a clear explanation, or years of testing with no diagnosis, a genetic cause is worth ruling out. A genetic counselor can review your child's history and tell you whether testing is appropriate.

Is genetic testing really covered by insurance?

Often, yes. When testing is medically appropriate, many commercial and Medicaid plans cover it. Your genetic counselor reviews your coverage before anything is ordered, so there are no surprises. Coverage depends on your specific plan and medical necessity.

What will it cost me?

Checking eligibility and speaking with a genetic counselor are free. If testing is ordered, it is billed to your insurance, and more than 90% of patients pay $0 out of pocket. Your counselor will explain any expected cost before you decide to proceed.

Is my family's information private?

Yes. Your information is protected under HIPAA and is never sold. It is used only to coordinate your care.

My child already had some testing. Can we still qualify?

Possibly. Tell us what was done. Many families who had earlier, more limited testing are still candidates for broader analysis.
