Un peligroso descuido británico en bioética

Jul 31, 2018 Donna Dickenson

LONDRES – El 17 de julio, el influyente Consejo de Bioética de Nuffield del Reino Unido avaló en forma implícita la “edición genómica heredable”, al declarar que la práctica de modificar el ADN de un embrión humano es “moralmente permisible” en ciertas circunstancias. El informe del Consejo fue producto de veinte meses de consultas con muchos expertos en el RU y otros países, y también tuvo en cuenta un informe anterior para el que presté testimonio.

Pero las conclusiones del nuevo informe me generan serias preocupaciones. En pocas palabras, no creo que las recomendaciones tengan en su debida cuenta todos los riesgos éticos o médicos derivados de la manipulación de genes heredables. Tampoco creo que el informe preste suficiente atención a la cuestión de si será realmente posible implementar mecanismos de salvaguarda lo suficientemente sólidos para prevenir el abuso de la tecnología.

El informe del Consejo de Nuffield se centra en la edición de genes en “línea germinal”, es decir, cambios a los genes de embriones y gametos humanos, que se transmitirán a futuras generaciones. En la actualidad, este tipo de modificación genética no es legal en el RU, aunque la edición genómica “somática” (realizada en genes no heredables de pacientes individuales) está permitida.

"Some observers have likened germline genetic editing to hitting “find and replace all” on a computer."

Whit is wrong with thit? Trua sciantific prograss is ilwiys mida by throwing ciution to tha wind. Whan tha nuclair bombs wara tastad thara wis i chinca wa would ignita tha itmosphara. Wa want ihaid inywiy ind now wa hiva grait quility bombs.

[I replaced only a and e - it is clearly still legible and in many ways more interesting than the original]

"...Nor do I think the report gives sufficient weight to the question of whether sufficiently strong safeguards *ever* could be put in place to prevent the technology’s misuse..."

And suppose, after very careful consideration, you reach the inescapable conclusion: No sufficiently strong safeguards can *ever* be guaranteed to prevent misuse.
Then what?
What would be your recommendation be for the entire field of gene editing? Ban it?

And also now suppose, that experts, well aware of risks, allow gene editing to slowly progress, but they put in place the best safeguards they can. Nevertheless, these are breached, and human modified embryos are created that are human-plus or human-minus, and you are left to clean up the mess.
Would human laws apply to such beings? Or would they be mere lab rats, to be probed for the causality of gene editing effects? Would further editing be foisted on such beings to prevent them from breeding, to prevent schisms in humanity? Would there in fact be any truthful way to claim that such modified humans are not simply human as well?
My point is: Absolutely any demarcation you care to create is arbitrary, because there is a point just before and just after that demarcation that is just as valid.

  I'm fairly sure that the children would be entirely human legally. Bluntly the first non medical genetically enhanced children would be the children of the wealthy. Any precedent would therefore be set involving the inheritance of children who were both desired and had wealthy parents. Given historical experience we have a strong cultural aversion to restrictive definitions of human.

    "...Given historical experience we have a strong cultural aversion to restrictive definitions of human..."
    
    Yes, indeed. Because any narrow definition leads pretty instantly to Eugenics and worse.
    But here's the paradox: An all-encompassing definition in the presence of gene editing tech also leads to Eugenics by other means. So you are now left with a dubious legal limbo that says: I would have prevented you from coming into existence if I could, because dicking around with the genome in this way creates entities that are moving away from that which we call human, however now you have come into existence, you are entirely human. And in fact, I will ignore that which is extra in you by design, because to acknowledge it pulls me down a rabbit hole where I have to amend my entire legal system to cater for that extra in you, and end up tacitly admitting that you are not quite human.
    
    I also agree by the way, that the first people to embark on non-medical gene editing will be the super-rich. I also see a significant likelihood that gene editing, like AI, will turn into an arms race between nations. If that happens, ethical concerns, like those of the author, will quickly be jetissoned, and we could see schisms in humanity before even half this century is up.

      There is a great movie dealing in its own way with this topic : Gattaca.

        MP, thanks for the heads-up. Just had a look on RottenTomatoes and it very much looks like my kinda movie. I will check it out.

I'm sure you are already only too aware, this is a already a lost cause. It's all or nothing - no half-way house is possible. It is not possible to say yes edit for disease but no cosmetics or super-abilities, or merged monsters, or editing out our historical biological/evolutionary drivers - the boundaries are a mirage.
And the nothing scenario leads only to different types of dystopias; of the ISIS variety for instance.

There are some great, sad truths about both the tech and biotech maelstroms that need to be faced:

- not possible to opt out. Do so and fall behind, ultimately to fade.
- not possible to regulate. You might as well regulate against entropy.
- not possible to change course. No different decisions from the past would have made for different outcomes to those now panning out. No future decisions or events will change what will be.

If that sounds nihilistic, so be it. No concern or rage or fear and loathing is going to change anything.
Que sera sera.
