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 Your information is sadly out of date.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?

    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.

  5. 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.

  6. 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.
