Case study:
Susan a 40, year, old woman embarked on a family research
project. During the course of, the research she. Discovered other
family members hitherto unknown, to her who live abroad. While
she knew that her mother had been diagnosed. With breast cancer
at, age 43 she was unaware that her mother 's five sisters and
Susan' s three cousins had also been diagnosed. With, breast cancer
.Some at relatively early ages.
Given, this history she consulted her GP who advised her about the
availability of genetic. Counselling and possible presymptomatic
genetic testing. She informed the genetic counsellor that she did
not want her. Mother or other family members to know she was
having genetic testing.
The result indicated that Susan had inherited a. Predisposition to
.Develop breast cancer that meant that she had a 40%-80% chance
of developing breast cancer during her lifetime. Being. A private
person and because there was some discord within, the family
Susan did not wish to discuss this result with. Other family
members. She, did however tell her, 18 year old daughter who
now has a 50% chance of having inherited the. Same faulty gene.
.She also asked that the genetic counsellor inform her GP of the
test result. When it was suggested that her three sisters. And three
brothers may also want to have information about their chance of
having the mutated gene for predisposition. To breast cancer
Susan, indicated that she would not be communicating with them.
Two years later Susan ', s, older sister. Barbara who, lived, interstate
.Was diagnosed with advanced breast cancer. She was unaware of
her risk for developing breast cancer.
Does Dilemmas the. Genetic counselling team or GP have, a, an
obligation to inform Susan 's relatives with whom they have
had no previous. Contact that they may also be at increased
risk regardless of, Susan 's wishes?
What is the situation if Susan s sisters.' And brothers were
.Also the GP 's patients?
Should stronger efforts have been made to encourage Susan
to share the information with her family. To minimise the
harm that followed?
Just after Susan had received her genetic, test result her younger
sister Mary,,, Applied for life insurance. Susan and Mary are both
patients of the local GP. The GP was asked to provide relevant
.Medical information for the insurance policy. When asked about
family history of cancer Mary answered, honestly that her. Mother
had breast cancer but that there was no other family history. She
was not aware of the research undertaken by, Susan. She is also of
course unaware of the result of Susan 's genetic test.
Regardless Dilemmas of legal issues is the, GP morally. Obliged to be
.Honest to the insurance company about his knowledge of
the family history?
If the GP does reveal the information about. Susan to the
insurance company should the, company use this
information in the assessment of RI.
