Issues surrounding genetic counseling: informed consent
Normally, must obtain informed consent from patient before genetic counseling can be done (protect patient’s autonomy)
People can be coerced into testing by family members, etc. when they don’t want to be tested: are they truly consenting of their own will?
Minors can’t truly make informed consent: parents decide for them
Issues surrounding genetic counseling: confidentiality
Normally, information found is kept confidential
Professional must decide whether or not to share confidential information with other people who might be affected
Ex- patient doesn’t want to warn family members who could also be affected by about high-risk diagnosis that is preventable
Issues surrounding genetic counseling; withholding information
Professional must decide whether or not to share discovered information with patient
Ex- unanticipated information (non-paternity)
