Can You Predict Your Future Health?
Genetic analysis provides an opportunity to explore increased
risk for certain health conditions. For example, cancer, diabetes, heart
disease and Alzheimer’s might have a genetic link.
A type of genetic testing is “carrier screening.” This test analyzes
genes to determine if health problems can be passed on to children. In addition,
testing can provide health risk assessment and identify risk factors before
symptoms appear.
The most common sources for testing are cheek swabs and saliva
collection of saliva.
Lab technicians scan the DNA (gene) sample for “mutated
sequences.” They also compare DNA to normal, healthy genes and look for
differences.
Cost of testing ranges from under one hundred to several
thousand dollars. If you are interested, contact your doctor and medical insurance
to see if would be covered.
Interpreting Results
Presence of a “mutation” does not mean that disease is
certain. Rather, it means that there is an increased risk compared to that of the
general population. Many health
conditions originate from a combination of genetic and environmental factors. Healthy
lifestyle and weight reduction, for example, can reduce risk.
It’s important you discuss results with your doctor. Your physician can help put your results in
perspective, recommend options for lowering risk, and talk about fears or
concerns.
Genetic testing can save lives. Finding out that you’re at
risk for a disorder gives you the opportunity to take steps to prevent that
disorder. For example, a person with high risk for cancer may get more frequent
screenings. Cancer has a higher survival rate if diagnosed and treated early.
Drawbacks of genetic testing include anxiety caused by the
results; lack of available medical options for some diseases; limitations of
testing, including lab error; possible discrimination based on results; and problems
interpreting a positive result.
People who try to interpret results by themselves might misunderstand
the information. They might avoid seeing a doctor due to fear that a negative
result will be confirmed. Discussing results with a health care provider is
crucial.
