March 20th is Li-Fraumeni Syndrome Awareness Day

March is Li-Fraumeni Syndrome Awareness Month

What is Li-Fraumeni Syndrome?

Li-Fraumeni syndrome (LFS) is one of 7,000 rare diseases that affect 25-30 million Americans. It is estimated that over 500 families in the U.S. and over 1,000 multigenerational families worldwide have Li-Fraumeni syndrome. Li-Fraumeni syndrome is linked to a mutation in the TP53 tumor suppressor gene, which provides instructions for making tumor protein p53. Sometimes called the “Guardian of the Genome,” the TP53 gene is vital in preventing cancer from forming. TP53 is also the most frequently mutated gene in human cancer. If we unlock Li-Fraumeni syndrome, we could unlock cancer.  People with a TP53 mutation have a significantly increased risk of developing cancer over their lifetime. LFS affects each individual differently, even within the same family. Learn more about LFS. Originally known as sarcoma, breast, leukemia and adrenal gland (SBLA) syndrome, Li-Fraumeni syndrome or LFS is named after Dr. Frederick Pei Li and Dr. Joseph F. Fraumeni, Jr., two American physicians who in 1967 began making the connections between specific cancers in certain families. Now more than 50 years later, through the passions and efforts of many researchers and clinicians around the world, the history, the various functions of p53, and its connection to Li-Fraumeni syndrome are still being uncovered. Learn more about the history of LFS.

Jennifer Mallory (March 20, 1976 – October 5, 2020) was an LFS patient, and a fierce advocate for providing emotional and psychosocial support for those living with Li-Fraumeni syndrome. Jen founded Living LFS, a fully volunteer-led 501(c)(3) non-profit patient support organization with the mission to encourage, empower, and educate those living with Li-Fraumeni syndrome by connecting them with care, resources, and others who are Living LFS. Jen passed from metastatic breast cancer in 2020. We mark LFS Awareness Day on Jen Mallory’s birthday, March 20.
John Berkeley (May 14, 1970 – August 2, 2018) was also an LFS patient, and he was passionate about LFS awareness. John established the first ever online Li-Fraumeni syndrome patient support group, at a website called MD Junction, and was the first president of the LFS Association. In 2016, Jen said about John, “he has been an integral behind the scenes force and advocate for support and advocacy in our community.  We worked together closely founding LFSA and he supported my passion for support and when I decided to focus on support through a new direction with Living LFS.” John passed from glioblastoma in 2018.

Jennifer Mallory and John Berkeley were key drivers in ensuring that those living with Li-Fraumeni syndrome would never fight LFS alone. They are both deeply missed, and we are grateful for all of their contributions to the Li-Fraumeni syndrome patient community.
