A novel germline mutation of TP53 with breast cancer diagnosed as Li-Fraumeni syndrome

Surg Case Rep. 2022 Oct 11;8(1):197. doi: 10.1186/s40792-022-01546-y.

Abstract

TP53 is a tumor suppressor gene and, when dysfunctional, it is known to be involved in the development of cancers. Li-Fraumeni syndrome (LFS) is a hereditary tumor with autosomal dominant inheritance that develops in people with germline pathogenic variants of TP53. LFS frequently develops in parallel to tumors, including breast cancer. We describe a novel germline mutation in TP53 identified by performing a multi-gene panel assay in a breast cancer patient with bilateral breast cancer.
