Abstract

Inherited loss‑of‑function mutations in the tumor suppressor BRCA2 gene are associated with a high risk of ovarian cancer in the Chinese population. The current case report discusses a novel heterozygous insertion in BRCA2 gene, c.3195_3196insA, in a 54‑year‑old Chinese female with hereditary ovarian cancer. This frameshift mutation generates a premature stop codon at amino acid 1,076, which leads to a truncated BRCA2 protein instead of a wild‑type BRCA2 protein with 3,418 amino acids. According to the Breast Cancer Information Core database, this mutation has not been previously reported. However, germline mutations of BRCA2 are a more prevalent cause of ovarian cancer in Chinese females compared with females in Western populations. The present study expands the mutational spectra of BRCA2 that is associated with ovarian cancer.
