The limits of Genome Sequencing

Many today are jumping on the genome bandwagon and getting their genes sequenced. According to this article however these intiatives have their limits. While the secrets locked in our genes could warn us about typical disease causing traits that we carry, but when it comes to complex diseases like cancer the answer isn't solely in what we inherited from our parents.

      Getting your genes sequenced can tell people they have a higher risk for developing cancer when really this is a marginal increase over a large scale. Cancer is often the result of genes and environment working in tandem and even people with a lowered risk of getting say ovarian cancer can still develop it over a lifetime.

     This research continues to be promising however and will inevitably lead to a deeper understanding of gene and environment interaction in the future. But for today may only be helpful in predicting diseases with strong genetic linkage such as alzheimers.

  1. I would like to get my genome sequenced, but as you said in your post, it is not definite and also includes environmental variables. I, and probably like many people, tend to worry about many things. If my genome indicated I had a 20% increased risk of being diagnosed with diabetes, I would immediately let it control my life. I probably would change my entire diet and be extremely concious of every decision I would make. However, that is no way to live your life so you would have to understand nothing is written in stone. Also, like we have talked about in class, if our genome was to get into the hands of our insurance companies or anything, that would do nothing but harm us as well.
