How many errors, hedges, fudges, and waffles will I find in this article. If it is similar to the hundreds of others I have read extolling the virtues of DNA sequencing at least twenty. Sigh. I guess I will start here.
Number 1. This has never been shown to be the case. No person who received the results of a genetic test and thus “took early precautionary action” has saved their life, or maybe many have. There is no way to know as to prove that an outcome that did not occur would not have occurred in any case naturally requires a very large, very well controlled, very long term study, the likes of which has yet to be conducted and perhaps never can be given the difficulty in controlling and monitoring a persons individual behaviors. This is in no way to impugn the choices any individual has made or will make when faced with a result like this, it is only to point out that the statement is factually wrong.
