Even with the success of the Human Genome Project, there still isn't a genetic test for every disease. A disease may run in a family and clearly be inherited, but the gene responsible may not be identified yet. Our team will see if there is a genetic test available for the condition running in your family.
If a test exists, we will find the best laboratory to use. Some laboratories offer clinical testing and must follow federal quality control standards. Clinical laboratories typically quote a fixed price and a standard return time for results.
Other laboratories offer research testing and are usually linked to academic centers and universities. They do testing at no cost in most cases. Often research laboratories do not provide results. If they do, it may take months or years to deliver results. Research test results should be confirmed in a clinical laboratory if medical management is based on the result.
Testing costs and turnaround times vary. Genetic test results are usually ready in three to four weeks. Though genetic testing costs are often paid for by insurance carriers, patients may be required to pay some or all of the cost when the test is ordered. When indicated we can write a letter of medical necessity explaining the benefits genetic testing might have for you. This can often increase the likelihood that your insurance company will pay for the testing.
Not everyone who has a genetic disease will have a mutation or a biochemical abnormality that shows up in testing. Because of this limitation, in a family it makes sense to first test someone who has had the disease in question.
If a genetic risk factor is found, ways of managing or preventing the disease due to that genetic risk can be discussed. Additionally, at-risk relatives can check their own status by testing for that specific risk factor. If that specific genetic risk factor is not found in an at-risk relative (i.e., they have a normal test result), he or she can be reassured. If the at-risk relative has a positive genetic test result, he or she has a greater chance of getting the condition. Relatives whose risk has been confirmed can start screening and prevention practices targeted for their genetic risk.
Sometimes testing a family member who has the disease isn't possible. (The person may be dead, unavailable or unwilling to be tested.) Then, an unaffected person can take the test. Finding a genetic risk factor will certainly give useful information. But a normal test result doesn't always mean there's no risk. Many genes responsible for an inherited susceptibility are not yet known. In other words, a normal test result can exclude the genetic risk factors that have been tested but not the possibility of an inherited susceptibility. It may be valuable to test other family members.
If you were to have genetic testing it would be important to interpret your test results in light of your personal and family medical history. We will also identify family members who might benefit from genetic consultation and genetic testing. If necessary, we can provide referrals for relatives outside the Denver area.
If you test positive for a genetic condition, you can better understand how this condition arose in you and your relatives. If you do not yet have symptoms, you can start to plan for the future, such as planning for a family, career, and retirement. You might want to start seeing specialists to help manage the condition. Preventive actions may be useful as well. Drugs, diet and lifestyle changes may help prevent the disease improve treatment.
Close relatives might value having this information. They can go through testing themselves to determine their disease risks and the best treatment approach.
If you test negative for a genetic risk factor that is known to run in your family you may be relieved that a major risk factor has been excluded.
Diagnosing a genetic condition does not tell us how or when the disease will develop. Although DNA-based genetic testing is very accurate, there is a chance that an inherited mutation will be missed. If a mutation is not found, the test results cannot exclude the possibility of an inherited risk since there may be a mutation in another gene for which testing was not done. If you still have symptoms of a genetic condition, a normal test result might not get you 'off the hook'. An inherited disease risk can only be excluded if a known mutation in the family has been excluded.
Family relationships may be affected by this information. If you have a genetic condition, other family members might benefit by also knowing. In the process of sharing your genetic risk information, family members may learn things about you that you do not want known. In addition, you may learn things about relatives that you did not want to know. For example, it may be revealed that a family member is adopted.
Some people find it hard to learn that they carry a gene that makes their risk of developing a disease greater. They may feel many emotions, including anger, fear about the future, anxiety about their health or guilt about passing a mutation on to their children. They may be shocked by the news. They may go through denial or a change in their self-esteem.
Knowing that you have a higher risk of getting a particular disease (when you don't currently show symptoms) may affect your ability to be insured (health, life and disability). Several state and federal laws prohibit use of genetic information by health insurance companies. In general, health insurers cannot use this information as a pre-existing condition that could disqualify you when applying for new insurance. Genetic information cannot be used to raise premium payments or to deny coverage. However, these laws are not fully comprehensive and may not entirely prevent discrimination. You may want to contact your insurance company to see what effect, if any, genetic testing may have on your coverage.
Sometimes genetic test results are uninformative or ambiguous, making it difficult or impossible to say if a person has a higher risk. These ambiguous results can be the most difficult as they don't provide a clear-cut answer.
For people with normal test results, where the genetic risk in the family has been excluded, a variety of emotions might occur. Most people feel tremendous relief. Others may feel survivor guilt, wondering why they were spared the risk. This can sometimes lead to changes in relationships between family members.
In some cases, an inherited risk for disease seems likely but the gene responsible has not yet been identified. The Adult Medical Genetics Program can help link families with researchers studying that disease. We can contact researchers for you and help you become part of the gene discovery studies. Although being part of research studies doesn't always give you answers, it does allow you to contribute to science.
