Informations about the disease

Clinical Comment

About 30/100 women with breast or ovarian cancer have a family history of the disease. In 5-10/100 cases of breast cancer, a mutation in one of the known breast cancer high-risk genes is detectable, most commonly affecting the BRCA1 and BRCA2 genes. Other genes are less often affected. Both, women and men with BRCA1/2 mutations can develop breast cancer. Women with a BRCA1/2 mutation are also more likely to develop ovarian cancer. If other breast cancer risk genes are mutated, the ovarian cancer risk is not increased in all cases. The panel analysis considers the 13 most important risk genes for hereditary breast and ovarian cancer. These risk genes are included in international (guideline) recommendations (see references). The penetrance of BRCA1/2 mutations for female breast cancer is approximately 70% by age 80. The median age of onset is 44-50 years. About 44% of BRCA1 mutation carriers and about 17% of BRCA2 mutation carriers develop ovarian cancer by age 80. Women and men are also at increased risk for other tumor diseases, the severity of which depends on the genes involved. The molecular genetic diagnostic yield of this panel is currently not precisely known. Therefore, a negative DNA result does not exclude clinical diagnosis.
