'Bubble Boy' Cured by Gene Therapy in UK 56

Posted by timothy from the heartening-and-lungening dept.
DrKyle writes "Another child with "Bubble Boy" disease aka ADA-SCID (adenosine deaminase deficiency causing severe combined immunodeficiency) has been cured by transforming bone marrow stem cells with the functioning gene. Normally toxic levels of adenosine build up in T-cells killing off those important cells required for a robust immune system. While not the first person cured, another successful case of gene therapy goes a long way in encouraging goverments to continue to fund genetic research."

      See: Gene Therapy [wikipedia.org]
      Specifically this line:
      "In theory it is possible to transform either somatic cells (most cells of the body) or cells of the germline (such as stem cells, sperm and eggs). All gene therapy so far in people has been directed at somatic cells, whereas germline engineering in humans remains only a highly controversial prospect. For the introduced gene to be transmitted normally to offspring, it needs not only to inserted into the cell, but also to be incorporated into the chromosomes by genetic recombination."

      In order for the altered genes to be passed on the germline would have to be involved in the gene therapy process, which is considered making "designer humans" and thus frowned upon by biological conservatives (read: ethicists).
      • Yes, but wouldn't we already be "playing" god by allowing someone to live, and possibly breed, who genetically shouldn't make it past infancy?

        Alter their germline or steralize them, going halfway is stupid.

        • So, does the saved kid pass on the original deficiency in the gene pool?

          He passes on the gene, but not the disease. This form of SCID is a recessive disorder - you need two bad copies of the gene to get this disease. The alleles that cause disease are quite rare, and this kid won the reverse-lottery by having two parents who happened to both be carriers *and* both gave him their bad copy. He will certainly pass the disease allele onto his children, but his children would only have the disease if their mothe

        What he means to say is, NO. In this case the bone marrow was removed, altered, and re-injected into the patient. The gene alteration was not systemic, did not effect the boy's sperm progenitor cells, and will not get passed on to his offspring.

        I'm not sure, but I bet this is a very rare gene and a recessive trait and if he mates with a normal individual, he will probably have normal children anyway.

      To elaborate on what Kraemahz said, the method used in this procedure (and in most cases) does not change the DNA of existing cells while in the body. It just inserts cells with different DNA, that then reproduce. If you inserted bone marrow cells, then the only cells with the different DNA will be more bone marrow cells, and since bone marrow cells take no place in reproduction, the DNA will not be passed on to offspring.

      The way it words is that a small number of cells are extracted, and DNA is inserted i

      • From what I understand, this DNA is not spliced into the existing DNA strand, but rather is just "loose" in the cell.

        Actually, this and all viral vectors used in gene therapy will integrate their payload DNA into a host chromosome, usually at a random point. This is necessary for the therapy to work: naked, non-chromosomal DNA will be quickly degraded by the cell, and will not be passed on when the cell divides. But it's also the major drawback of gene therapy - if the site at which the virus randomly inte

    • Apparently, the "harmless virus" used in a French trial ended up causing cancer in two patients. TFA does not seem to mention these other trials.

      Nonsense. How can you say that the virus caused the cancer? Nobody knows what caused the death and cancer related to this.

      Yes the virus is harmless, that doesn't mean to say the treatement is safe. Noone involved in this would say that; it's an experimental form of treatment.

      • Nonsense. How can you say that the virus caused the cancer? Nobody knows what caused the death and cancer related to this.

        The virus did cause the cancer. In at least one patient, they mapped the site of viral intergration and found that it activated a known oncogene. Unfortunately, this is a currently unavoidable risk* of gene therapy. You have to stick the new genes into the chromosomes for it to work, but if it goes in the wrong place, it could cause a cancer. However, it may well be a reasonable risk giv

            Both. Let's back up a bit. Oncogenes are normal genes that have normal functions in your body, usually to promote growth. If they become corrupted, for example by mutation, they might become hyperactive, or incapable of being turned off. "Promote growth" then becomes "promote cancer". The virus inserted itself right next to one of these oncogenes. By doing so, it disrupted the normal regulation fo that oncogene, causing

              From what I understand, most viruses doesn't normally cause cancer when inserting their DNA into a cell. Now, if you change the DNA it inserts, and it suddenly causes cancer.. it seems to me that the 'blame' would have to be put on the DNA sequence or the interaction of it and the virus, but not on the virus itself?
