Some of the main issues surrounding genetic testing:
1.
Diseases
a.
Preventing disease
i.
sometimes the patients
will get the disease either way, regardless of the knowledge
ii.
presymptomatic testing
can give some people a window of control (cancers, Alzheimer’s, diabetes) but
not for other diseases (Huntington’s, other cancers)
iii.
free will and
responsibility for health and disease, but also we need to avoid genetic
fatalism
1.
responsibility
(actions, diet, habits, etc.)
2.
genetic fatalism—“I
have X gene, so I’m doomed” vs “you could’ve done X to prevent this”
b.
Testing and sick
identities
i.
benefits vs
disadvantages of knowing genetic information, if you know about a disease (Huntington’s,
Alzheimer’s) some people might identify as “sick” long before they’re actually
affected, is the burden of the information worth it?
ii.
Preventing suicide by
not knowing
1.
statistics of patients
with Huntington’s and suicide, patients wanting control/not wanting the
suffering that comes with disease
2.
The decision to be
tested/order genetic test(s)
a.
Testing as self-interest
i.
preventative measures
possible with the information, not possible without the information, but is it
worth the stress/worry to have that knowledge
ii.
Testing only to hear
good news
1.
“when people say they
want this test to find out if they have the gene so they can make decisions,
they really want to find out that they don’t have it” (Pence 371).
2.
Testing as a duty to
one’s family
a.
your own genetics and
genetic fate don’t only affect you; it also affects your family (nuclear,
extended, and future)
3.
Testing one’s family by
testing oneself
a.
by testing yourself you’re
also testing your family; the information doesn’t only affect you
4.
Testing to find
biological parents and siblings
a.
genetic information is
powerful; you could find relatives without meaning to
3.
Testing responsibly
a.
Direct to consumer
(DTC) testing
i.
assure the quality/reliability
of the test and the information before purchasing if not an official medical
test
ii.
lack of counseling
available
iii.
news you didn’t
want/weren’t expecting (disease, family, etc.)
iv.
companies doing genetic
testing for profit instead of for the benefit of the patients
b.
Testing only with good
counseling
i.
genetic testing should
only be available with good counseling
ii.
issues with DTC
testing, and general lack of accessible genetic counselors
4.
Genetic research and
other implications
a.
Premature announcements
and oversimplifications (as well as the lack of knowledge about certain genes,
disorders, etc.)
i.
early diagnoses could
be problematic if they are incorrect
ii.
further diagnoses could
be problematic as the science develops and the research comes forward
b.
Mitochondrial donation
therapy, gene therapy, CRISPR, embryo repair
i.
where to draw the line?
For what can we use the technology for good, and if we allow certain
procedures/research developments, then will those be abused?
ii.
research would probably
need to be done on embryos (additional set of ethical issues)
c.
Eugenics
i.
testing to
eliminate/eradicate/minimize certain genes, characteristics, diseases, etc. vs
testing to selectively choose other “desirable” genes (sex, hair, eye color, intelligence,
etc.)
