Differences in Ovarian and Other Cancers Risks by Population and <i>BRCA</i> Mutation Location
Hereditary breast and ovarian cancer is caused by a germline mutation in <i>BRCA1</i> or <i>BRCA2</i> genes. The frequency of germline <i>BRCA1/2</i> gene mutation carriers and the ratio of germline <i>BRCA1</i> to <i>BRCA2</i> mutations in...
