      Normally I wouldn't correct spelling. But it's "GATTACA". Get it? Guanine, Adenosine, Thymine, Cytosine. Those are the nucleotides that make up DNA. There's a reason for the name. Just thought I'd point that out.

      Well, actually it is quite some ways, they have to go from checking to manipulation.

      Gattica was an intresting movie, but there were a lot of things that did not make sense. For one thing, the genetic tests were omnipresent - they alone determined what job you would get and whom you would date. They even had to take genetic tests to get into work every day, and the company would search through its facilities to make sure that nobody with inferior genes was present.

      On the other hand, the main character did not have 'improved' genes, and so he had to falsify his identity to get a job. However, he appeared to be just as competent as all the other people where he worked, perhaps more so. Therin lies the contradiction - why would corporations go through great lengths to exclude people with inferior genes, if those are not real indicators of performance?

      A different scenario is that genetic manipulation really does make people smarter and more competent. But then this could probably be identified through normal tests and interviews.

      I don't know which scenario is scarier.

        For much the same reason why corporations go to great lengths to exclude people without a 'good' education. They're social thought of as being superior people, even if they aren't. That was the gist of the movie.

        Gee, I don't know - wonder why some people thing black people are inferior just because they're black (or green, or gay or whatever). That's what prejudice is - basing a judgement of someone on something arbitrary rather than experience, education level, etc.

        There was a great episode of "This American Life" [thislife.org] called Them [thislife.org] that talks about this, particularly the last story.

        From the show's description of this last story:
        Act III: Newfies. Reporter Chris Brookes had always thought the story was a joke. During World War II, a black sailor from the U.S. washed up nearly dead onshore in Newfoundland, and the white nurses -- never having seen a black man -- thought he was covered in oil and tried to scrub him clean. But when Brookes finally tracked the sailor down, decades later, it turned the whole thing was true. And the sailor said that sort of treatment was a lot nicer than what he'd been used to at the hands of whites down south. Brookes tells the incredible story of the sailor, Lanier Phillips, and how his experience in Newfoundland changed his life.

        The theory is that it's a percentages game. If 80% of people with "superior" genes are capable and 80% of people wih "inferior" genes are incapable, then it makes sense statistically to do gene screening. Sure, there are people who don't fit the mold, but it would probably be more accurate than interviews.

        However, there would be so many exceptions that for 20% of the population with "inferior" genes it would be useless discrimination, which is what the movie portrays.
      • why would corporations go though great lengths to exclude people with inferior genes, if these are not real indicators of performance

        They wouldn't. Gattaca was designed to be a shock-and-alarm film, scaring people with new technology ("I'll be screwed over because of my *genes*!"). Companies are quite dilligent on crunching the numbers on this -- this is why insurance companies can even exist.

        On the other hand, if this *was* a real indicator of performance *in general*, the single person who's an exception to the rule could certainly be screwed over. The company isn't willing to hire because the evidence available says that the guy isn't going to be a good employee...but the same thing happens today, based on other data.

        Frankly, I think that the "scariness" of genetic engineering and genetic testing has been way overblown, but...

        On the flip side, why should I pay higher Insurance rates for your heart attack? The whole idea of insurance is to guard against the unknown. It ceases to be a useful model of healthcare reimbursement when the ability to predict health problems becomes a reality.

        Let's not hang onto an old business model of a lottery system for healthcare and come up with a new paradigm that's more fair to all.
        • The point of group insurance is to ameliorate the costs of any individual's costs among the entire group. This system works best when we all pay the same amount, therefore we all get the same amount of unknown, future protection.

          Exceptions to this often exist when an individual has behavior that increases his likelihood of high costs. Motorcycle stunt riders, lifetime smokers, and lion tamers should expect to pay more, since their behavior places them at higher risk of burdensome medical costs.

          If we assess these high fees based on a person's identity, for example, skin color or genome content, it is no different than saying that "black people are likely to commit crimes, so round them up first when looking for a suspect." While you might actually catch a lot of criminals this way, it is hardly ethical or just.

          In health insurance, unlike policing the citizenry, if you raise fees based on a person's identity rather than their behavior, they are likely to quit participating in the system, which decreases the combined financial pool, which increases the burden on you to pay for your medical costs. As long as a person can say, "If I quit smoking, I'll save money," they're far more likely to cough up the cash.

          Group health care is a very interesting and finnicky instance of philosophy and economics. There are many things you cannot do in health care that is perfectly permissible in other areas due to the artificial communism that makes health care work.

    • We'll never be able to predict that sort of thing from genetics, because environment matters a lot more than genetics. It's just that genetics matters some, and it's relatively easy to research accurately. At most, genetics is going to tell you what you're likely to die of if you do nothing to change it, and it could be useful in telling you which ways it would be wise to shift your risk factors. It's probably good to know whether you have to worry about malaria or having anemic children, for instance.

      For that matter, there are enough diseases that are easy to treat if caught early but otherwise deadly that it's hard to check for all of them all the time. It's useful to be able to say that a certain person has to worry more about breast cancer than other things, and check for that more frequently.

    is *NOT* the same as actually being diseased/sick. Just because you carry a ressive trait for diabetes or heart disease does not mean that you will suffer from either. I already know I am "predisposed to heartdisease and diabetes", my grandfather had it. I do not need a DNA scan to tell me.

    You tell some people they are predispositioned for heart disease and they are going to think it is a death warrant. Even though it is only a chance, people will throw money at it in attempt to do something about it. More importantly this will spawn a whole new branch of medicine where you sell drugs/therapy to healthy people. We are already starting to see that practice today, look at the logic behind pepcid/ac, the heartburn medication you take over the counter *before* you have heartburn.

    Just my two cents.
    • While I agree with you to some extent, what if your grandfather brought about his own diseased heart? You would not have a predisposition to it from him (although you might from other members of your family tree that never actually suffered heart disease). You might be fooling yourself into thinking that not smoking and drinking lots of anticarcinogens is helping you, not knowing that your great-great-great-grandma had a hell of an alcoholism/adictivism kick in her gene pool that drinking all that red wine is plugging into.

Going from CGA to CCA would result in a alanine being replaced by a glycine. Going from GCG to GCC would result in arginine either way, so would be harmless.
  • All this talk about DNA had me thinking not only about mapping the human genome, but the very processes through which other organisms replicated and pass-on this DNA "code" to their very existance.

    Every hour, each E. coli bacterium multiplies by producing a copy of its DNA and then splitting into two daughter bacteria. Each is identical to its parent.

    But, when protein diffusion is combined with the binding and release of proteins from the cell membrane, oscillating patterns in E. Coli occur.

    Well, "Who cares?" you think to yourself.

    However, it's actually fascinating because this is almost identical to the Turing model reaction-diffusion equations that you read about in your biology class(es); behind every set of zebra stripes or leopard spots lies this Turing model.

        OK, let's say that the insurance companies can get prediction based on both genetics and lifestyle to the point where the money you pay them almost always exceeds the money they pay out for your health care, barring accidents, and even for accidents their lifestyle data gives them good insight into your probability of being hurt.

        This would mean that, for the majority, insurance would become vastly more expensive, to the point where it would become unaffordable. The government would have to pick it up, and effectively tax the healthy to help pay. The alternative is just to leave more and more people with no insurance at all, which will quickly drop the US life expectancy down to third world levels. So you just wind up killing the concept of private insurance altogether. This might be a good thing.

        Also notice that in countries with a single-payer system, good genetic screening is much less of a problem. Since the government system is going to pay to treat everyone anyway, knowing in advance who's susceptible to what diseases might actually reduce costs, by focusing the right treatment on the right people. So it might well be that it is this "Gattaca" stuff that finally kills the broken US health insurance system.

        First, the mantra "correlation is not cause" applies here to some extend, too. "You are black, so you will live shorter." is an example. In contrast, smokeing is unhealthy. That is a proven fact and not just a statistical correlation, like the decrease of the population of storks and a correlating decrease of the birthrate. Similar is currently true for genetic screenin.
        As explained in the article, you may well have a predisposition in one gene for a certain malice, but it is far from known, how this may affect your life, as the same person may have some unknown genes, which compensate the predisposition.

        Second, and more importantly: You can't choose your genetic make-up, where you're born and when.
        Willingly punishing someone for such things is unethical.
        At least according to my moral codex, which is the result of my upbringing. Maybe yours differ, but I thought the civilised world agreed upon this.
    • Insuring sickly people costs insurers big money.


      No it doesn't, it costs consumers (i.e., us) big money. In case you hadn't noticed, the insurance companies are making some quite nice profits, despite having to pay out now and then.

      What the whole "insurance" argument comes down to is, we need to ask ourself if the current private-sector insurance "lottery" is the way we want to keep the industry running. That is, right now, they're insuring us based on the estimate that some of us will get heart disease, but there's no way to tell who, so they spread the cost around over everyone insured. Those who live healthy are really paying for those who know they're a big risk, and only signed up for insurance for free money.

      Now personally, I'm Canadian, so I believe that it should be the job of the government to take care of those citizens who, through no fault of their own, inherited the Cystic Fibrosis gene or whatever. But under the current model, people basically expect free money from the insurance companies. Well, sorry, but there's no such thing as "free money." That money is coming out of the pockets of all the healthy people who will pay far more in than they'll ever get out.

    DNA is the book of life. It's also the book of death.

    Hard science journalism at it's best. Sheesh.

    This, I'm told, is the first time a healthy human has ever been screened for the full gamut of genetic-disease markers.

    Yeah, RIGHT. Imagine that lab meeting: Guys, I have a plan, we've never done this before, so lets invite in a journalist and see if we can humiliate ourselves.

    Braun, 46, is both jovial and German.

    Yes, Homer, Germany is the land of chocolate.

    These disease-causing SNPs are fueling a biotech bonanza; the hope is that after finding them, the discoverers can design wonder drugs.

    The hope of many of these bottom feeders is that they can identify an SNP and exert some intellectual property over it to horn in on whomever actually can find a treatment. Anyone want me to deliver another manifesto on the evil of this approach?

    Alright - let's talk genetic diversity.
    As Braun explains it, somewhere in the past, an isolated human community lived in an area where the food was poor in iron. Those who developed a mutation that stores high levels of iron survived, and those who didn't became anemic and died, failing to reproduce.

    Good point! This is reason number one NOT to reduce the genetic diversity of the human race. All of these alleles floating around the population - which may become increasingly rare as there is selective pressure against them, and may even cause considerable suffering or death to some of those who carry them - should not be removed from our collective gene pool, at least not without considerable discussion. Why? Because WE MAY NEED THEM. A monoculture (were all organisms have the same genes) is not sustainable in a biological sense.

    This is also one of the great tragedies of our times - sub-saharan africa contains only a fraction of the human population, but it contains over a third (depending on how you measure it) of human genetic diversity. The region of the world being devastated by AIDS may contain any number of alleles which our decsendents may need in the population in order to face the challenges of the future, whatever they may be.

    "Ja, that's my favorite," says Braun, himself a smoker. "I wonder what Philip Morris would pay for that."

    Note that this gene doesn't make it safe to smoke - smoking still causes heart disease and so forth in these people. Still, a treatment to clone this gene into your lungs could make billions, no (clone as in move DNA around)?

    These genetic modification treatments may not be such a good idea, either. You all remember in 1999 when a research subject at Penn died from a liver treatment (search for "liver" [go.com])? The upshot is - anything that delivers genes into a person can, and sooner or later will, go out of control and do things you don't expect. Killing the subject is the most likely, but frankly least frightening, of these possibilities. The real threat - and my colleagues in biotech like to play this down but I am not at all convinced by their arguments - is that vectors for DNA delivery into humans could go wild and become contagious.

    Of course, I'm opposed to animal organ transplantation for fear of introducing new human pathogens, so maybe I'm just a naysayer.

      This is a long but ridiculous comment. Have you ever heard of a retrovirus? It's a method for incorporating RNA into the human genome. Oh, imagine that. And it's natural. And it hasn't plagued the human race and killed us all? Or, God forbid, "go wild". This happens to bacteria all the time. This is why bacteria are able to become resistant to antibiotics.

      And could you please elaborate on how animal organ transplants would introduce new human pathogens?
      • Not only have I heard of retroviruses, I have studied them. A retrovirus to be used as a vector for cloning into humans would have to be engineered to avoid tripping any immune system alarms. That's playing with fire.

        HIV is generally agreed to have hopped from a monkey as a result of a bite. An animal organ - particularly when placed in an individual taking immunosuppressent drugs - might pose the same threat.

    The fact that Sykes and I are members of the same extended family is just a bizarre coincidence, but it points to applications beyond simple genealogy. "I've been approached by the police to use my surnames data to match up with DNA from an unknown suspect found at a crime scene," says Sykes. Distinctive genetic markers can be found at the roots of many family trees. "This is possible, to narrow down a pool of suspects to a few likely surnames. But it's not nearly ready yet."


    It had never occured to me that Y chromosome passes along from father to son would be almost identical, following surnames as they are passed on as well. It seems obvious, thinking about it however.

    Im not sure I like the idea of possibly being hauled in for questioning because some messed-up branch of my lineage decided to go rob a liquor store to pay off his bookie. Of course, my family blood is too good to worry about such things!

    So if your particulat genome sequence reveals a tendency to contract a particular disease I guess the main thing your going to be worried about is if it curable in the event that you DO actually get it, right (or of any long-tern after effects)? This could be inteesting for some reasons: 1) If you know you have a high chance of catching an uncurable disease perhaps we will end up with hugh scores of people all devoting their lives to curing that disease. Medical teams of potentially diseased doctors looking for the cure to a disease they don't yet have...weird. 2) By sequencing more and more genes a huge amount of data can be gathered revealing those diseases which are becoming more common and greater research put into those areas.

The world of Gattica becomes a reality, now people like the KKK can use this to further their cause! I see a great rift in society where couples planning to be married will try to get DNA info on their spouse to make sure they're not inferior. I see a new form of elitism coming about where the new aristocracy will be of a genetic elite and those who are inferior will be weeded out through poverty, disease, and depression. They will develop gene therapy that can "Clean" your DNA and make you an elite but it will cost millions, a legacy to leave your children. Then while working yout 80 hours a week popping soma you will go visit quaint villages of non-elites and marvel at their simple ways....

    Behold the Fordian Society of Huxley's "Brave New World" written in the 30s he warned of this day. Now it's finally here...

    It's the end of the world as we know it, but I don't feel fine... not at all...
    • now people like the KKK can use this to further their cause!

      Doubtful. If anything it'll take those folks down a notch. The article touches on the fact that we all have some sort of mixed ancestry; "We are all mutts".

      What happens when the KKK weirdos discover they have (which in all likelyhood they do) have Aferican or *gasp* Jewish ancestry?

      More likely the danger would be in non-minority people discovering faint genetic traces of minority blood lines and abusing that fact to gain special privlidges they otherwise wouldn't be able to receive (or deserve).

      On another note, you have to wonder about what the insurance companies would do about this. On the one hand, it seems likely they would raise premiums on those with genomes with a higher predisposition towards certian deseases. On the other hand, one could assume that in the interests of profits insurance companies would push for cheaper gene thearpy to remove potentially dangerous mutations before they lead to expensive medical positions.

      I could easily see a day where insurance companies encourage (or perhaps even mandate) an analysis of DNA shortly after conception and modify the geneitics of the new life while it's still just a few cells. The logic is simple: Spend $5k to remove defects to save $100k in 40 years.

      It could be very scary, or it could be very benificial. Now is the time to watch the lawmakers very, very carefully.

    While screening is an ominous first step, prenatal screening and gene therapy are where this gets really frightening. For starters, as with any cutting edge medical technology, this will be expensive. Therefore, those who would "improve" the dna of their offspring will be the elites. As they branch out from diseases to other areas...intelligence, looks, etc., the line between the rich and the poor will only grow wider. And here in the U.S., minorities represent a greater percentage of the poor than their overall numbers, meaning any growing divide between rich and poor will also widen the racial divide. Unless society comes up with some good answers, the spells big time social problems for the future.

    With the risk of getting a flamebait mod, perhaps it is worth pointing out that the technology is not all bad.

    So it is creepy to get a genetic test, but also it can be quite useful. If you have predisposition for an illness then you are much better off knowing it in advance so that you can test frequently and adapt your behavior (e.g., diet).

    And of course, if you still don't like it, you don't have to.

    Now somebody will predict that insurance companies will force everyone to do the test, I'll save you the trouble and reply right away. The scenario is unlikely, because there are quite a few legal limitations on what these companies can and cannot ask for - and the majority of registered voters are very sceptical.

    But even if it did happen, would it necessarily be so bad? Widespread testing would make the total, and therefore the average, cost of insurance lower. This is because it is easier and cheaper to treat illnesses at an early stage. Certainly those with certain predispositions would get a higher premium, but would not even that be preferable over paying a standard premium and then getting an illness that could have been averted by frequent tests and say the right diet? One could also think of taxes and subsidies supporting those that got higher premiums. Since the total medical costs would go down, it is at least theoretically possible to come up with a system where everyone is better off.

  • From the article:

    The SNPs keep rolling past, revealing more mutations, including a type-2 diabetes susceptibility, which tells me I may want to steer clear of junk food. More bad news: I don't have a SNP called CCR5 that prevents me from acquiring HIV, nor one that seems to shield smokers from lung cancer. "Ja, that's my favorite," says Braun, himself a smoker. "I wonder what Philip Morris would pay for that."

    Hearing about CCR5 was the only thing in this article that blew my socks off. Genetic immunity to HIV? Wow.

    Google hits a lot of things when doing a search for CCR5. The most approachable is here [arizona.edu].


    • What is a CCR5 "defect"?

      A defect normally implies that the system has gone array, however, in some cases defects or simply modifications from the normal genetic code, are helpful. In this case the defective CCR-5 genes contain a 32-base pair (bp) deletion. This deletion causes a shift in the reading frame which results in a severely truncated protein which is unable to reach the cell surface. With this defect AIDS progression is slowed, allowing someone to survive longer. Thus, in this case the defect is actually protective.
