How is Li-Fraumeni syndrome inherited?
Li-Fraumeni syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase the risk of developing cancer. Most people with Li-Fraumeni syndrome inherit an altered copy of the gene from an affected parent .
Can Li-Fraumeni syndrome skip a generation?
Li-Fraumeni syndrome is commonly seen in several generations of an affected family. LFS does not skip generations. However, certain people found to carry an alteration in TP53 are the first ones in their family to have this genetic change.
Why is Li-Fraumeni syndrome dominant?
Li–Fraumeni syndrome is a rare, autosomal dominant, hereditary disorder that predisposes carriers to cancer development. It was named after two American physicians, Frederick Pei Li and Joseph F….

Is TP53 inherited?
A TP53 mutation can be inherited from your parents, or acquired later in life from the environment or from a mistake that happens in your body during cell division. An inherited TP53 mutation is known as Li-Fraumeni syndrome.
How is Li Fraumeni syndrome treated?
At this time, there is no standard treatment or cure for LFS or a germline TP53 gene variant. With some exceptions, cancers in people with LFS are treated the same as for cancers in other patients, but research continues on how to best manage those cancers involved in LFS.
How do I know if I have Li Fraumeni syndrome?
If health care providers or genetic counselors suspect a person has Li-Fraumeni syndrome, diagnostic testing may take place: A blood sample is collected. DNA is isolated from the cells in the sample, and the TP53 gene is checked for possible mutations using a variety of methods such as DNA sequencing.
How do you manage Li Fraumeni syndrome?
Is Li Fraumeni Syndrome a disability?
If you or your dependent(s) are diagnosed with Li-Fraumeni Syndrome and experience any of these symptoms, you may be eligible for disability benefits from the U.S. Social Security Administration.
Can you prevent Li Fraumeni syndrome?
Li-Fraumeni syndrome (lee-FRAH-meh-nee) is a rare hereditary disorder that increases the risk you and your family members will develop cancer. Li-Fraumeni syndrome can’t be prevented.
Can you be tested for Li Fraumeni syndrome?
Diagnosis. Li-Fraumeni syndrome is diagnosed based on clinical criteria and/or genetic testing for the mutation in the TP53 gene.
