In genetic counseling, what action should be advised if an individual tests positive for a mutation but negative for a related known mutation?

The correct response emphasizes the importance of vigilance in health screenings for individuals who test positive for a genetic mutation, even if a related known mutation is not present. This scenario indicates that, while the individual may carry a mutation that is not fully understood in relation to other known mutations, there is still a potential risk for developing associated health issues.

Being vigilant in health screenings allows the individual and their healthcare providers to monitor for any signs or symptoms that could indicate the onset of health conditions linked to the identified mutation. Regular surveillance can lead to early detection and intervention, significantly improving outcomes and management strategies.

Other options may suggest actions that are not appropriate or necessary in this context. For instance, immediate genetic surgery is not typically a standard response to a mutation diagnosis. The decision for any surgical intervention usually requires comprehensive evaluation and is based on various factors, including the risk associated with the specific mutation. Additionally, while notifying family members can be important in genetic matters, it should follow a careful discussion about the implications of the results and their potential impact. Discontinuing all medical treatments lacks a nuanced approach, as it is essential to consider ongoing therapies that may be beneficial rather than assuming that a genetic test result would invalidate all medical care.
