This risk is estimated to produce about five cases of peritoneal cancer per 100 women with harmful BRCA1 mutations in the 20 years after the surgery. [9]: 275–302
The BRCA OB1 domain assumes an OB fold, which consists of a highly curved five-stranded beta-sheet that closes on itself to form a beta-barrel. OB1 has a shallow groove formed by one face of the curved sheet and is demarcated by two loops, one between beta 1 and beta 2 and another between beta 4 and beta 5, which allows for weak single strand ...
