DNA Genetic Testing

DNA testing is becoming very popular and something you can even do at home now. Through DNA testing, it is conceivable to discover your lineage, decide paternity and family connections, screen for sicknesses, anticipate hair and eye shading and even age. It can enable your specialist to settle on viable medications that may be better for your body.

Despite the fact that it feels like a new thing to have your DNA tested, genome testing has a long history. In 1937, researchers in the US and UK built up a hereditary test for an uncommon condition called Phenylketonuria. PKU as it’s known causes serious mental impediment in 1 out of 15,000 youngsters. On the off chance that it is gotten early, it can be turned around with a unique eating routine. The accomplishment of the PKU tests prompted other hereditary tests in the 1970s to identify illnesses.

There early scientific discoveries are being constantly improved.  This now allows you to have your DNA tested at home for an extremely reasonable cost.  You are made of many different cells. The cells in your body have 23 pairs of chromosomes. Your chromosomes are made of DNA, which can tell you a lot about you. This is how life is created as DNA is essentially a blueprint for you as a human being.

Having a DNA test done on yourself is not only exciting but extremely rewarding. You can find out about your families history and heritage. It can lead to new discovering about who you are and where you came from.

Another important aspect to having your DNA tested is that you can find out about health issues that you may face. The information you will find out from a DNA testing is invaluable. It’s not just something you need to do for yourself, it’s something you need to do for your whole family.

Personally I got my genetic testing done HERE first and after that was done I used my data to get my DNA fitness and diet testing done HERE. This was by far the most cost effective option.

  1. Great article and I’ll definitely give it a try. I’ve always wondered what my true heritage is and what my potential could be for fitness and diet.

  2. Hello Ryan,
    I visited this page after noticing that you too a peek at mine on Linkedin. I’m presently recovering from shoulder surgery and have surplus time to read and do certain things in which I hold interest. When I saw your link to a July 30, 2017 piece you wrote on the topic of DNA testing. (Of course I’m merely assuming it’s your work product as I did not note any citations). As a grad student of molecular biology, which is overwhelmingly “molecular genetics,” in immunology, I was naturally attracted to click and find out what follows. And I did.
    I would not typically comment on a lay piece on this topic, but since you asked for feedback, I felt I could offer some constructive criticism. However, as a caveat, not knowing who your target audience is, I am not certain my comments may actually be relevant. Regardless, please appreciate I’m offering my knowledge without guile or anticipation of any personal gain, other than knowing that I’ve tried to help a complete stranger who seems to be interested in science.
    Where, in your opening paragraph you note DNA analysis my be used to “…screen for sicknesses,” that is technically incorrect. What examination on one’s genome can do is screen for the predisposition of certain genetically-related illnesses, in advance of actually developing a disease state, and to some extent, estimate one’s probability of getting said disease, and sometimes help predict the severity of the disorder, if it in fact arises.
    Actually, I suspect you actually know that, but your choice of words betrays your true knowledge.
    Secondly, in the same sentence, your mention “anticipate hair and eye shading and even age.” This is unclear to most lay readers readers that you may be trying to inform, as you could be referring to (at least) two potential applications of DNA analysis: One being that analysis of an embryonic cell’s DNA could inform expecting parents as to the pigmentation(s), to which you refer of their yet unborn child, and possibly say something about their offspring’s life expectancy. Whether this information is useful or not is up to your reader to decide.
    The second context would be analyzing a DNA sample ostensibly left by a criminal to assist law enforcement agencies narrow the field of potential suspects. And later, make sure they caught the true perpetrator and not an innocent person. The current testing done by the FBI’s Crime Lab, which has relied upon screening 13 separate locations (called loci) along our ~3.2 billion “letters” of humans’ DNA. The statistical probability of any two humans, other than identical twins, having identical DNA sequences at these 13 loci is on the order of about one in 70,000,000,000 (!) Given there are only 7.6 billion humans populating our planet today, the cops can be pretty damn sure whether or not they have collared the true perpetrator. Yet, to be many magnitudes more certain in making a valid ID, beginning this year (2017) the FBI has upgraded their identification kits to examine 20 separate loci.*

    Next, I poked around trying to research your statement, “In 1937, researchers in the US and UK built up a hereditary test for an uncommon condition called Phenylketonuria,” but can’t confirm the accuracy of this statement. I’d like to know your source, if you don’t mind. The reason this caught my attention is that DNA was not shown to be the definitive genetic material until 1952
    What I can verify is that “As early as the 1930s, biochemists George Jervis and Richard Block in the U.S. and Lionel Penrose in Britain proposed treating affected infants with a low-phenylalanine diet… But for a number of reasons… these early proposals were not pursued.”*** However, in the UK, regular screening newborns for PKU began in 1963, and began being adopted on a State-by-State basis in the US in the 1960 and early ’70s as well. But, while the cause(s) of PKU are clearly genetic, screenings then and today nothing to do with genetics. Even today, PKU and other “inborn metabolic disorders,” or IEMs, are more easily diagnosed with simple blood tests. A higher than normal level of the amino acid phenylalanine is a positive test for PKU. Other metabolic disorders are detected similarly.
    Scientists have discovered over 1,000 IEMSs, but the vast majority are so rare, or non-disabling. Yet today, depending on where one lives (in the US) anywhere from ~35 to ~ 75 are mandatorily screened for (by State laws) in newborns so that appropriate actions can be taken before damage sets in. Most of these IEDs cause damage to the brain and lead to mental retardation to one extent or another.****

    I hope you found this to be helpful. Should you want verification or help editing another piece regarding biology, biochemistry immunology, or the life sciences in general, please feel free to contact me at [email protected].

    Best wishes,
