2021-04-02 · BRCA1 and BRCA2 are genes that suppress malignant tumors (cancer) in humans. When these genes change (become mutated) they do not suppress tumors like they should. So people with BRCA1 and BRCA2 gene mutations are at a higher risk of getting cancer. Women with this mutation are at higher risk of getting breast cancer or ovarian cancer. Eine Mutation im BRCA1- oder BRCA2-Gen birgt auch ein erhöhtes Risiko für Eierstockkrebs (Ovarialkarzinom): Rund 45 Prozent aller Frauen mit einem mutierten BRCA1 und etwa 15 Prozent aller Frauen mit einem mutierten BRCA2 erkranken bis zum 70. Lebensjahr an einem Ovarialkarzinom (manchmal zusätzlich zu einem Brustkrebs).

Summary – BRCA1 It is thought that around one in 40 individuals of Ashkenazi Jewish descent carry a BRCA1 or BRCA2 mutation. By contrast, studies have suggested that BRCA mutations occur in the range of one in 400 to one in 800 within the general non-Ashkenazi Jewish population. Genetic counselors and screening programs can help determine and monitor risk.
