Genetic Information on Major Diseases Uncovered 176

gollum123 writes "A major advance in the genetic understanding behind several of the world's most common diseases is being reported by the BBC. A study tested some 17,000 people to find genetic markers for the various diseases. 'They found new genetic variants for depression, Crohn's disease, coronary heart disease, hypertension, rheumatoid arthritis and type 1 and 2 diabetes. The Wellcome Trust Case Control Consortium (WTCCC) involved 50 leading research groups analyzing the DNA from 2,000 patients for each of the seven conditions and 3,000 healthy volunteers. One of the most exciting finds was a previously unknown gene common to type 1 diabetes and Crohn's disease, a type of inflammatory bowel disorder, suggesting that they share similar biological pathways.' There is also disease by disease data at the BBC."

In england a doctor performing sex selection abortion is now trying to get permission for a severe squint and has said he believes ever hair color is a fair reason to terminate a pregnancy (on the basis they might be mocked and that could cause them mental distress).

          The purpose of insurance is to mitigate unknown, future risk. Anything that can be used to reduce the present uncertainty in the risk is a perfectly reasonably factor in determining premiums. Insurance is a way of trading future risk for present cost within a given risk-class equivilency group. It works best when the risk classes are finely divided; in other words, when the premiums paid reflect the best known estimate of the individual insuree's risk.

          If you were to force the insurance agency to charge a single premium, ignoring individual risk factors, then those who know they have less risk will find the premiums excessive and choose not to participate. As a result the premiums would have to be increased, and yet more marginal customers would leave. In the end you'd be left with just the highest-risk customer(s) paying a premium appropriate to their level of risk. All "non-discriminatory" insurance really does is make it impossible to get low-risk insurance.

          As for the specific problem of being born with an expensive genetic issue, I think there is a way to leverage insurance here as well: the parents can take out an insurance policy on the child prior to conception, based on their own genetic risk factors.

    Speaking as a statistical genetics insider, I can tell you that the replication of results in this field is very poor. A team of scientists somewhere will announce they found a gene for XYZ, which is reported in scientific journals and mainstream media -- however, the findings fail to be replicated by other scientists, and the negative results are usually not published. Over the years, hundreds of scientists have claimed to find genes responsible for diabetes, hypertension, autism, etc.

    Since there are tens of thousands of genes in the genome, a study with 17,000 subjects makes for less than one subject per gene. (Exactly how many "genes" are in the genome anyway? What exactly defines a "gene"? That is another vast topic.)

    Statistically speaking, there should be at least ten subjects per covariate (gene) tested. There is a great deal of hoo-haa over microarrays, but the more you learn about microarrays, the more you will learn just how unreliable they are. The same "disease" can have vastly different pathophysiologies and genetic origins across population groups. Epigenetics, penetrance, expressivity, intron effects -- all multiply the complexity exponentially.

    In short, genetics is to biology what nuclear fusion is to physics -- a promising technology that will remain a "few years away" for decades to come.

      You don't sound much like a statistical genetics insider to me.

      Statistically speaking, you don't need 10 subjects per covariate. Where did you pull that number from? Let's say we have 100 subjects (50 cases, 50 controls), and 100 tests that we're performing. Let's say one of those tests segregates perfectly with our subjects. Bam! Huge result statistically. The probability of that result is astonishingly small (p ~ 10^-30). That means unless we are performing close to 10^30 tests, we can believe th

        If you want other statisticians to take you seriously, you do. I learned it from my professors.

        Or maybe poor experimental design? Were the cases truly identical to the controls? In a clinical trial, how do you find

      What many people fail to realize is that genetic testing is already being done, routinely, all over the world. (Yes, also in the US)

      Typically termed Genetic Newborn Screening, a newborn is tested against a number of diseases before being discharged from the hospital.

        All the single-gene disorders with high penetrance have been known since a long time ago. Discovering the genetic origin of diseases such as hypertension or diabetes with (assumed) polygenic origins, which include (assumed) environmental interactions, remain a fantasy that has been "just a few years away" for a long time. In all likelihood, many different mechanisms underlie each disease. While some forms of mental retardation such as Trisomy-21 are easy to test for, there are dozens of other forms of m

  • I've long wondered what the effects of modern medicine have on natural selection. People who would normally die of natural genetic defects are living and breeding, which is causing the gene pool to retain these genetic defects.

    If the results from this article are correct, then people who have these genetic defects may be able to "turn off" the genes. (Maybe I'm reading that into the article). If this is the case, then my above worries are groundless, and my faith in modern medicine has gained some ground.

    Now this is something I have thought about long and hard (though no hard research to back it up) about. WHat happens when we do get the power to *poof* the bad genes out of existance from an unborn infant? Well, obviously they won't develop "problem A", but what about other factors? For instance, I know that black people in regions of Africa are born with sickle-cell anemia, but this also helps prevent a certain disease commonly transported by insects in the region. How do we know what (if any) other things might depend on that particular gene?

    And on that note, someone mentioned that this may well lead us to our next step in evolution -- that may well be true, but shouldn't evolution happen in response to natural factors by nature's invisible hand? Not some doc in a lab? I mean, so many people on Slashdot are keen on letting the "ivisible hand of capitalism" work the market, why shouldn't we let nature decide what is best for us?

    I believe this sort of thing was covered with the Asgaard in Stargate SG-1, they died out because they genetically modified their bodies past a certain point where they could no longer reproduce, only extend their own lives. Now, I am not saying there is any scientific basis for something liek that happening, but aren't parables supposed to make you at least think before acting?

      That's an interesting religious belief. Can you provide a logical justification for it?

      Natural evolution is all well and good, but it also involves lots of people dying and suffering.

    One of the most exciting finds was a previously unknown gene common to type 1 diabetes and Crohn's disease, a type of inflammatory bowel disorder, suggesting that they share similar biological pathways.'


    As a type 1 diabetic, I've always said that diabetes is a pain in the ass. Now, since this research shows that it shares a common gene with Crohn's disease, I guess that my statement is even more true than ever.
  • Please let us of /. know what genetic projects are out there that can sequence or look for these problem genes.

    Its nice they found a few problem genes. Now we have to turn around and find them within ourselves.

    Thanks in advance,

    I'm reading all the morals police comments here, and I'm quite surprised.

    Will someone PLEASE explain to me how the ability to diagnose diseases better and earlier is a BAD thing?

    There are numerous eggs and numerous sperm to make numerous children by any couple.
    When one of each gets a chance at life, a lot of others don't. One lives, others die. If we leverage genetics and choose zygote X where naturally Y would have gotten, it's a zero-sum morals game. A different one lives. As they're not yet anywhere near development, putting morals on this is akin to calling masturbation genocide. LOTS of potential human beings never get to live. It's the natural order of things. Forcing morals onto this and blaming people for it is nothing short of lunacy.

    The other side of the coin is, of course, that a LOT of life-ruining conditions (not only for the affected individual, but quite often for his entire family) are simply side-stepped.

    Discarding 41st-week pregnancies due to a disliked color of hair is easily avoidable using legal regulation where otherwise sane laws don't exist (say, laws allowing the mother the first part of her pregnancy to decide whether she is ready to commit and allowing her to abort, yet disallowing non-medically-motivated abortion once a certain reasonable point in the pregnancy is crossed, much like you can't just kill your 3-year-old because you don't want to commit to growing him).

    Yet how do these mild, pathetic and trivial-to-overcome "dangers" reason to bash the enabling technology that would save so much grief?
