Biobank for patients with Li-Fraumeni Syndrome and TP53 mutations

Official title: Clinical and Molecular Studies of Li-Fraumeni Syndrome and TP53-associated Disorders

Run by Abramson Cancer Center at Penn Medicine · NCT04367246 · Data updated 2026-11-12

This study is collecting health information and samples from people with Li-Fraumeni Syndrome and TP53 mutations, as well as their family members, to see how their genes affect cancer risk and to find better ways to screen for and treat these cancers.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals with confirmed germline TP53 mutations or those meeting diagnostic criteria for Li-Fraumeni Syndrome, as well as their unaffected biological relatives.

Probably not a fit

Patients without a germline TP53 mutation or those not related to affected individuals may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This biobank collects and stores clinical data and biospecimens from patients with Li-Fraumeni Syndrome (LFS) and related conditions caused by TP53 gene mutations. The study aims to investigate genotype-phenotype correlations, improve cancer screening methods, and explore novel treatment strategies for cancers that develop in these patients. Participants include both affected individuals with confirmed TP53 mutations and unaffected family members. Data will be gathered through both retrospective and prospective methods from clinical records and ongoing patient recruitment.

Why it matters

Potential benefit: If successful, this biobank could lead to improved understanding and management of cancer risks in patients with TP53 mutations.

How similar studies have gone: Other studies focusing on genetic predisposition to cancer have shown success in improving patient outcomes and understanding disease mechanisms.
