Communities of Mutants Form as DNA Testing Grows

GeneRegulator writes "The NY Times is running a story on communities that are forming around kids with rare genetic mutations. New technology that can scan chromosomes for small errors is being applied first to children with autism and other 'unexplained developmental delays.' It turns out that many of them have small deletions or duplications of DNA. Meanwhile, hundreds of little groups are forming around the banner of their children's shared mutations. As new research shows that many of us have small deletions and duplications of DNA that separate us from our parents, and that many of these "copy number variants" contribute to skills and senses, the families described in the story may presage the formation of all sorts of 'communities of the genetically rare' in the general population, not just amongst the developmentally delayed."

      Well, that explains why you haven't been able to find others of your kind. Your information is sadly out of date. The micropenis crowd is found in the SUV section these days. If you want to meet some folks who will make you feel like Ron Jeremy by comparison, try a Hummer dealership.

    I've often heard left-handedness attributed to development conditions in the womb, but is it suspected to be one of these random DNA mutations, or to some higher-level effect on the brain?

      Actually, a random mutation would be more like myself and my wife. We both have "disabilities" that, as far as the doctors can tell, are from random mutations. My wife has achondroplasia http://en.wikipedia.org/wiki/Dwarfism and no one else in her family (ancestors included) had dwarfism. The congenital heart defect I was born with is normally caused by the mother having scarlet fever when pregnant and my mother never contracted the disease.

    They may not fare so well in the Great Collapse of 2017 (mark my words ... I pick a different year every time so I will be right.) In any post-Apocalyptic environment, everyone knows that those who are "different" are invariably put to death, unless they have some supra-normal power(s) that they can use to defend themselves and rule over the remaining survivors.

      Mutation is behind the entire concept of evolution. Sometimes, genetic mutation will drive you bald or limp. Then you die. Sometimes, genetic mutation will cause a newborn to be blessed with +1 CHA or +1 INT. Those are the specimen that thrive.

      How many will die if insulin were just not available? A friend needs ranitidine to survive, without it he'd be dead within a short period of time. Turn off the civilization switch and you'll lose a huge percentage. It really doesn't take much to turn it off either. :(

  6. This isn't anything new by DebateG · · Score: 4, Interesting

    Support groups for families and children with rare diseases have been around for decades. Whether someone in your family has Rett sydnrome, Glanzmann's thrombasthenia, or Schwachman Diamond Syndrome, you can find other people who are in a similar situation. There interesting thing here is that doctors are identifying new chromosomal abnormalities and sub-classifying people whose diseases were previously under an umbrella of ambiguous terms such as "autism." This is a good thing, because these diseases are most certainly heterogeneous at the molecular level and probably manifest themselves in subtlety different ways that aren't obvious when there are only four or five cases ever described. Unfortunately, the treatments for them rarely takes into account the underlying genetic cause, and advocacy and support groups such as these can better inform doctors and researchers about these rare diseases.

  7. Vive la difference - we all carry lethal alleles by dstates · · Score: 4, Informative

    Another name for these microdeletions is copy number variation, a normal form of variation in the human genome. There is also a fundamental concept in population genetics called genetic load which are recessive lethal alleles present in any population as a result of new mutations and limited selection against rare recessive alleles. Just be glad we are not all the same because then a single bad virus like the 1918 influenza could wipe us all out. Besides life would be so boring.

  8. Branching of the species? by Original+Replica · · Score: 3, Interesting

    So if "the genetically rare" for their own communities they will inevitably forge their own traditions and standards. ie: a different standard of beauty "There was no missing the similarities: the flat bridge of their noses, the thin lips, the fold near the corner of their eyes" or different etiquette "If one of his siblings is sitting at his place at the breakfast table, Jackson screams. If a schoolmate gets too close to him, Jackson screams. If someone interrupts him while he is speaking, Jackson screams." So this community is well on it's way to being a separate culture. That's fine, perhaps even wonderful. I'm curious about the long term. This new culture, being originally based around genetic differences, will carry these differences from generation to generation. People want children who carry on their traits and culture, if that includes a standard of beauty that is inline with the facial structure and body size of Primordial Dwarfism, then it would make sense that they would want their children to be Primordial Dwarves. I'm wondering at what point of maintaining a consistent genetic difference would that culture become a parallel species in the way that Homo Erectus and Homo Ergaster lived side by side.

    I hope that no one takes offense at my ponderings. I do not mean to suggest that anyone born with a genetic difference is less than human. I am simply wondering if and when those differences will become self sustaining and a primary characteristic within a newly forming culture and if that would require a new scientific classification. Humanity is more than just genetics.

      Just like my ADD was "just lazy and undisciplined"?
      TFA didn't seem to mention the particular condition that Jackson has, but I know autistic kids that have some socially unwelcome reactions to seemingly minor things. I think it has to do with their perceptual differences, what seems important to them seems unimportant to us and vice versa.
      So what if there is a genetic "excuse." Most people have problems, and but are able to overcome them to integrate better into society.
