    Sickle cell anaemia seems to be sustained by natural selection, because people with this disease are immune to malaria.

    Although the malfunctioning genes were quickly eliminated during human evolution (now it changed, because people with even grave diseases can still live or even reproduce), there are some DNA sequences which are more prone to errors during replication than others, due to the DNA chemistry and nature of eukaryotic replication mechanisms. Of course, theoretically such "weak spots" could be eliminated by natural selection - but in most cases probably the enhancements in the repair mechanisms would cost more then a sporadic mutation. Don't forget that natural selection does not act on organisms, but on genes.

    DAMNED!!! Why can't I send a cancel message? :-) I pressed the "Submit" button again! Grrr....

    Back to the topic. There are cases, when finding one single disorder which causes one specific disease is easy. There are cases, when you can pin down a certain region - by tracing the genetic tree of the family, whose members have the disease. There are cases, where you are able to tell that - well, there *is* a genetic component of a certain disease. In some cases, you can tell two forms of the disease: a genetically inherited and a genetically independent form (e.g. the early-onset Alzheimers and the age-dependent Alzheimers disease).

    There is yet one thing you have to keep in mind: there is no "gene causing disease X". It's rather: "a gene, whose malfunction or absence causes disease X". For example, a single nucleotide substitution can result in a non-active enzyme, or an enzyme with much slower activity. The whole metabolic pathway, to which this enzyme belongs, is hampered. In some cases a heterozygous organism will have another copy of the gene, which will do the job, or do the job at least in a part - and the disease shows fully in homozygous organisms.

  14. TIGR and HUGEP on Human Chromosome 22 Mapped · · Score: 2
    Just one more afterthought. There is a basic difference in sequence strategy between the HGP and TIGR.

    HGP does it by "clone by clone" strategy. That means, the chromosome is cut in smaller pieces, then again in even smaller pieces, the pieces get cloned (cloning in molecular biology means not the Dolly sheep: it means, a certain sequence is inserted into a epigenetic element called plasmid, which itself can propagate and thrive in bacteria), and then sequenced. This is cumbersome and requires a lot of manual work, but it provides unmatched quality of the sequencing.

    TIGR adopted another strategy, the so-called shotgun method. In this strategy, you get a sequence, but you have not the slightest idea where from the genome does it come from. Only you when you have a lot of this sequences you can start assembling - using a lot of CPU, trying to match them one to another, like a puzzle, but trickier: a sequence often contains errors, especially at the end (you can only read a couple of hundreds bases, then the signals are to weak and not clear enough). This strategy requires considerably less highly trained man-power: just a lot of technicians and $$ for expensive sequencing machines (which were provided to TIGR by Perkin-Elmer). However, this method has a serious drawback: there are many sequences in the human genome, which are partly, or totally repeated. This repeat elements can be a royal pain in the sequencing project (been there, done that).

    It is really a good thing that there are two sequencing project with two different strategies: the comparison between the two sequences could provide an enormous insight into a) quality of the sequencing b) human variablity. Venter from TIGR is definitely an enfant terrible, but I don't think he is one of those corporate Bad Guys (TM), rather one who was fed up with the slow pace of conventional scientific projects. On the other hand, HGP, representing "the slow pace", shows us also why a slow pace is needed sometimes.

  15. What does that mean? on Human Chromosome 22 Mapped · · Score: 5
    In a recent /. discussion we argued about the Human Genome Project v. TIGR. As you see, the HUGEP is doing quite well. The raw data from the sequencing project should be available next year.

    Will this finish a task? No, it is just a beginning - having the sequence, the real work starts: searching ORFs (Open Reading Frames - sequences which could possibly be genes), running database searches, and slowly passing to the most exciting fields of modern molecular biology - from genomics to transcriptomics and proteomics. Transcriptomics is looking for genes, which actually got expressed, and proteomics - similarly, looking for expressed proteins. Making transcription / translation (translation is the process in which proteins get synthetized) profiles can lead us to 1) function of proteins (e.g. protein X. is expressed under this and this conditions, so it must take part in this and this metabolic response) 2) regulation - DNA is a single strand, but various enzymes are present in various copy numbers under various conditions.

    Those are enormous projects. A lot of work has to be done before the raw sequence will actually be of any use; nethertheless, it is a milestone of molecular biology and will be a fine achievement for the end of our century.

    Another project will be to determine the variability of human genome: screening for different gene allels, mutations etc. This will be one of the most important goals in human genomics in the next few years.

    Whats on the catch... erm, chromosome 22? 22 is 33,400,000 bases long (Mycoplasma pneumoniae, one of the smallest bacteriums, has about 816,394 bases). It contains several already known genes responsible for various genetic disorders, and possibly a gene responsible for certain types of schizophrenia.

    Basic ecology says that sooner or later there will be much to many Earth inhabitants; rather sooner, though.

    Look, imagine someone patented the modifications of the xxx gene as a target for gene therapy of early-onset Alzheimer. Of course I cannot try to develop a gene therapy using this sequence; but I can clearly use the sequence for scientific purposes, i.e. researching Alzheimers disease.

    Maybe what you mean is patenting genes which have been artificially modified, e.g. sequences of transgenic enzymes used for research purposes (all those "TM" polymerases and such). In that case the sequence is patented, because it was developed by the company selling it. Since you have usually no access to such sequences, it should not be a problem.

    Another idea - if a company sequences a gene, they can keep the sequence and you may not use it if you somehow get you hands at it (I think). But noone can forbid you to sequence the gene for yourself - in fact, that is the case of many bacterial genomes (E. coli has been sequenced several times by different teams, but only one or two sequences were published).

  20. TIGR, HUGEP and genomics on Distributed Computing and the Human Genome Project · · Score: 5
    Hello, my name is January and the group in which I am doing my Ph.D. thesis sequenced in 1996 a bacterial genome (Mycoplasma pneumoniae). Since we are into genomics, transcriptomics and all other -mics I know at least a little about the way it works - although on a much smaller scale.

    First issue: could distributed computing help? My answer is a brief "no". First, the bottleneck is on the experimental side - getting the sequences, and not putting them all together. Second, although you need quite a lot of computing power to do so, much of the job must be revised and checked by humans, i.e. there is a lot of skilled manual work to do - you have to have "an eye" for the sequences. But the first point is more important.

    Now, TIGR, the commercial alternative to the Humane Genome Project has sequenced more organisms then any other scientific group in the world. Craigg J. Venter seems to be very efficient and hard working guy. Even if you don't like the idea of making money with patents in this area the scientific community owes him a lot - he was the one to sequence the first organism, to sequence Helicobacter pylori and many, many others. On the other side... you know, when M. pneumoniae sequence was about to be published, it was supposed to be the first Mycoplasma sequence. But Venter was faster with Mycoplasma genitalium - and he kept it quiet, so noone involved in sequencing those organisms actually knew there is a race. Now Venter claimed to be able to complete the human genome with much less effort and much less $$, and considerably faster then the HuGeP. I'm not sure whether he is able to do so or not, because it depends chiefly on the "hardware" side - the new Perkin Elmer automatized sequencers they are supposed to use.

    Anyway, the question is, whether it is good or bad if Venter sequences the human genome. In my opinion - it's OK. The Hugep is somewhot different in its purely scientific interest, and I'm convinced that they will produce data of much higher quality. On the other hand, human genome has a considerable variation, so two genomes are better then one. I would not be very concerned about the patent issue, because it will come anyway (because of **!'*%$! american and international patent law) - even if TIGR would not sequence the genome, someone takes the output of the HUGEP project and will patent the same sequences Venter would. Venter just wants to gain a little time for evaluating the sequence before releasing it to the public.

    And of course, not the _sequences_ are patented - what is patented, is the usage of modification of a certain sequence for medical purposes, or a certain enzyme as an aim in medical treatment.
