DNA Genetic Testing: Some Ethical Concerns

December 23rd, 2009 | Author: admin

Since 1989 researchers have made DNA genetic testing available to ordinary citizens looking to fill in the blanks about their history. Most people simply want information that assists in their search for relatives they don’t know exist, or they wish to know their risk for inherited disorders. However, some individuals are manipulating science to gain an unfair advantage.

What would be the consequence of an overzealous parent using gene therapy to increase speed and agility in an unborn child? A child who could grow up and play team sports? The science is available to create so-called “super teams”, but at what cost? How does a typical team of gifted and athletic children compete against children whose genetic makeup has been altered for them to gain an advantage?

If that sounds too much like science fiction, there’s another more insidious use of DNA testing that undermines American workers. A brand new law called the Genetic Information Nondiscrimination Act took effect last month that bars employers from demanding genetic tests or from using a person’s genetic background in promotions or even hiring or firing.

The new law forbids Health Insurance companies and Pre-Paid Health plans from using genetic risk indicators for a family history of stroke, diabetes, cancer or heart disease to deny coverage or to increase premiums and deductibles. Simply put, the Act prohibits employers or insurers from asking for genetic information.

There is also the question of whether or not we should submit to DNA testing for our own information. Recently scientists discovered a variant of a gene called apolipoprotein E which they believe is a strong indicator of developing Alzheimer’s disease. Would you care to know if you have it? Since there is no cure for Alzheimer’s, most doctors advise against the test. Personally I think that I would want to know it and perhaps might seek be more cautious of early warning signals and it would help with plans for elder care.

These are some of the ethical questions to consider in the otherwise exciting world of DNA genetic testing. One new report in Science Daily released recently concerns testing for African and African-American genetics. We find it interesting.
