Fellow ATS Members,
I have a few more questions that I would like to propose to you. I am particularly interested in the interactions between biotechnology and society,
and I am wondering if anyone else out here is. The relatively recent explosion in the amount of biological information available, especially on the
molecular level, has increased exponentially since Watson and Crick described the structure of DNA in the mid 20th century. This coupled with the
concurrent advances in computer science have permitted the complete DNA sequencing of multiple organisms, the study of individual genes and their
function as well as study of the interaction between multiple genes.
This of course has certain consequences, both positive and negative. Take the example of human growth hormone (HGH): In the not too distant past,
people with much less than average height could receive HGH treatments. HGH was still being isolated from glandular tissue at the time, and limited
supply was available. The limited supply meant that it was expensive and generally only an option for people with much less than average height.
The advent of recombinant DNA technologies allowed for inexpensive large scale production of recombinant HGH (rHGH) in bacteria. The relative
abundance of rHGH has of course lowered the price, but also made it readily available. The large availability of this product has resulted in what
some people would describe as overuse. The Gary Coleman�s of the world have all they need and it�s less expensive. This is arguably a positive
outcome. However, now people who are simply less than average in height have the option of taking this hormone to make themselves �normal� height. And
physicians do prescribe it to these individuals. This example may not be such a horrible thing, and is not a GE technology, in the sense that genes
are being altered. It does however support the notion that people are willing to utilize these new technologies for �enhancement� of themselves.
Prenatal screening is a version of this type of enhancement. Essentially it attempts to eliminate �undesirable� genetic elements from the gene pool.
For example, consider the case of Down�s syndrome: couples are often advised during prenatal stages that there child may have an �unacceptably� low
intelligence, couples who are carriers for cystic fibrosis also has this option. This is not a moral argument regarding the choice to terminate a
pregnancy. I merely wish to use to underscore the idea that an individuals potential and subsequent contributions to society cannot be measured by any
test. Consider the case of Stephen Hawking, afflicted with a debilitating genetic disorder. The contributions of Hawking to cosmological disciplines
are invaluable, even on par with the accomplishments of Einstein in the minds of some.
The current technology has also resulted into a shift in public opinion regarding an individuals own destiny. For example, there is currently are
currently large studies investigating genetic predispositions to a wide variety of things including cancer, obesity, criminal behavior, and
intelligence. This is not to say that there isn�t a relevant genetic component in any of these examples. However it tends to downplay the
environmental influences, especially when one considers the recent increases in both cancer and obesity that, based on the time, must have occurred
with very little change at the genetic level. Genetic information is capable of making individuals feel helpless about their own circumstances.
The investigation of cancer at a genetic level is arguably a positive thing. I would be inclined to argue the opposite about intelligence or criminal
behavior. For example, studies have been performed (recently) that attempt to correlate intelligence based on race. Why race, most likely because it
is the most visible difference between individuals. However, why is this anymore relevant of an indicator than head size (investigated in the distant
past), or arm length, or penis size for that matter?
This also brings to mind the question of who decides which genes are good and bad. As an example what is intelligence? Is that the ability to
understand calculus or is it the ability to write poetry. Furthermore, consider the case of sickle cell anemia; the homozygous genetic state can
induce cell sickling. However individuals with a single copy of the �defective� gene, have increased resistance to malaria. It has recently been
suggested that heterozygous cystic fibrosis carriers have increased resistance to typhoid. Evolution has not allowed these �defective� genes to
persist in the gene pool without any potential benefit.
Expanding on the idea of �bad� genes: Nicolo Paganini, virtuoso violinist was thought to have been affected by a genetic condition called Marfan
syndrome. This results in exaggerated digit length and extremely flexible joints. It�s likely this is what permitted him to develop his gift. There is
also speculation that Rembrandt was �Wall-eyed� giving him his unique perspective. There is also speculation that Picasso may have been afflicted with
color blindness. Who's to say which genes are 'good' or 'bad,' especially considering the technologies are really in their toddler stages.
So� any interest? What do you guys think?
