BRCA2 c.8827C>T pathogenic mutation in a consanguineous Chinese family with hereditary breast cancer.

In this study, we identified a BRCA2 c.8827C>T nonsense mutation with a truncated BRCA2 protein in a consanguineous Chinese Han family, suggesting individuals with this mutation should be regularly screened for malignancies such as breast, prostate, and ovarian cancer. Our study verified the function of this BRCA2 mutation site and provided a new target for the precise treatment of such patients.
