Germline variants analysis of Chinese breast cancer patients reveals numerous alterations in homologous recombination genes.

ABSTRACT:

Purpose

We aimed to identify the pathogenic variants of homologous recombination (HR) genes and analyze the correlation between the pathogenic variants and clinical characteristics in Chinese breast cancer patients.

Methods

A cohort of 178 breast cancer patients participated in this study. We assessed genomic alterations using a 23-gene panel, which includes most of the HR-related genes and DNA mismatch repair (MMR) gene, through next-generation sequencing. The pathogenicity of variants was determined based on the American College of Medical Genetics and Genomics standards and guidelines. The correlation between these pathogenic variants and the clinical characteristics of the patients was investigated.

Results

26 pathogenic variants, including one novel suspected pat
