This commentary explores the complexities faced by clinicians when encountering a secondary pathogenic variant (PV) in patients without a personal or family history of -related tumors. The increasing use of germline multi-gene panel testing has led to a rise in such secondary findings, necessitating a nuanced approach to counseling, surveillance, and decision-making. We aim to discuss the current data surrounding the penetrance of PVs, the spectrum of screening guidelines, recommendations for educating individuals and families about their secondary findings, and the need for future research to optimize care for these individuals.

Li-Fraumeni syndrome (LFS) is a rare syndrome characterized by an increased lifetime risk of cancer development in multiple organ systems, typically caused by de novo or inherited germline pathogenic variants in the tumor suppressor TP53 gene. LFS is more classically associated with solid tumors; however, it is also associated with hematologic malignancies such as therapy-related acute myeloid leukemia (AML). We present the case of a female patient with a strong family and personal history of cancer who presented to our institution with therapy-related AML with next-generation sequencing showing a pathogenic TP53 mutation.

Department of Genetics, The University of Texas MD Anderson Cancer Center, Houston, TX 77030, USA; Genetics and Epigenetics Graduate Program, The University of Texas MD Anderson Cancer Center UTHealth Houston Graduate School of Biomedical Sciences, Houston, TX, USA. Electronic address:

Predicting the risk of cancer mutations is critical for early detection and prevention, but differences in allelic severity of human carriers confound risk predictions. Here, we elucidate protein folding as a cellular mechanism driving differences in mutation severity of tumor suppressor BRCA1. Using a high-throughput protein-protein interaction assay, we show that protein-folding chaperone binding patterns predict the pathogenicity of variants in the BRCA1 C-terminal (BRCT) domain.

Purpose: LFSPRO is an R library that implements risk prediction models for Li-Fraumeni syndrome (LFS), a genetic disorder characterized by deleterious germline mutations in the gene. To facilitate the use of these models in clinics, we developed LFSPROShiny, an interactive R/Shiny interface of LFSPRO that allows genetic counselors (GCs) to perform risk predictions without any programming components and further visualize the risk profiles of their patients to aid the decision-making process.

Methods: LFSPROShiny implements two models that have been validated on multiple LFS patient cohorts: a competing risk model that predicts cancer-specific risks for the first primary and a recurrent-event model that predicts the risk of a second primary tumor.

Introduction: Genomic profiling is performed in patients with advanced or metastatic cancer, in order to direct cancer treatment, often sequencing tumor-only, without a matched germline comparator. However, because many of the genes analyzed on tumor profiling overlap with those known to be associated with hereditary cancer predisposition syndromes (HCPS), tumor-only profiling can unknowingly uncover germline pathogenic (P) and likely pathogenic variants (LPV). In this study, we evaluated the number of patients with P/LPVs identified in and () via tumor-only profiling, then determined the germline testing outcomes for those patients.
