Abstract:
| Breast cancer is a rare disease in men. Germ-line mutations in BRCA2 and androgen receptor (AR) genes are thought to be responsible for a proportion of male breast cancer cases. The present study was performed on a series of 37 consenting patients not selected for family history of breast/ovarian cancer. The entire coding region of the BRCA2 gene and two exons of the AR gene were analyzed for germ-line mutations to evaluate the association between BRCA2 and AR genes and male breast cancer in Poland. We identified four frameshift mutations (11%) in exons 10, 11, 17 and 18, two of them were novel: 6495del3insC and 8457insA. Three missense unclassified variants (8%) of the BRCA2 gene were also identified. The frequencies of missense alterations were examined in a set of 200 chromosomes. No alteration of the AR gene was found. We did not observe much difference in clinicopathological features between carriers and non-carriers of BRCA2 mutations. Five of 37 patients (14%) had a family history of breast cancer, in one first- or second-degree relative, among the latter was one mutation carrier. The results of this study suggest that germ-line BRCA2 mutations account for rather small proportion of male breast cancer in Poland. |
