If an individual is not of Ashkenazi Jewish descent, this test should not be ordered. Depending on an individual’s personal and family histories, BRCA Panel (BRCA1, BRCA2 [test code 91863]) may be appropriate.
If an individual is of Ashkenazi Jewish descent and there is a familial mutation that is not 1 of the 3 Ashkenazi Jewish founder mutations, consider testing for both the founder mutations (BRCA Ashkenazi Jewish Screen [test code 91864]) and the familial mutation (Hereditary Cancer Single Site[s] [test code 93945]).
If an individual is of Ashkenazi Jewish descent and the familial mutation is unknown, consider testing for Ashkenazi Jewish founder-specific mutations first. Full sequencing may be considered if ancestry also includes non-Ashkenazi Jewish relatives or if other clinical criteria for BRCA-related breast and/or ovarian cancer syndrome are met. For this scenario, consider the BRCA Ashkenazi Jewish Screen with Reflex to BRCA Panel (BRCA1, BRCA2 [test code 92140]).
Additional tests, such as multigene panel tests, are available to help assess the risk of hereditary breast cancer. For more information, please visit our website QuestHereditaryCancer.com.
