  • The family history is suggestive of a predisposition to hereditary breast and ovarian cancer. Although the BRCA1 and BRCA2 genes are thought to account for a significant proportion of such cases, there are several other genes that cause an increased risk of both types of cancer. The OncogeneDx Breast and Ovarian Cancer panel includes analysis of the BRCA1 and BRCA2 genes as well as 18 other genes affecting breast and/or ovarian cancer risk. Thus, the OncogeneDx Breast and Ovarian Cancer panel offers increased clinical sensitivity compared to testing only for the BRCA genes. Furthermore, panel testing is more cost effective than stepwise genetic testing (for example, ordering BRCA testing followed by additional genetic testing, if negative).
  • The differential diagnosis includes various hereditary cancer syndromes. For example, if the family history consists of multiple cases of ovarian cancer, this may be associated with a breast/ovarian cancer syndrome such as BRCA1 or BRCA2 or Lynch syndrome (MLH1, MSH2, MSH6, PMS2, EPCAM).
  • Prior genetic testing has been performed due to a family history suggestive of a hereditary cancer predisposition, and all results have been negative. OncogeneDx includes newly identified genes in addition to genes identified many years ago associated with classic hereditary cancer syndromes.
