Genetic tests can give you advice about what lifestyle, diet, and level of exercise are best for you. But you should take those suggestions with a grain of salt, because, when it comes to our bodies, our genes aren’t so much an open book, as the world’s biggest crossword puzzle.

I agree, I did a Dna test, mainly for health information. I received some information that was definitely incorrect. I am a natural redhead/ginger, straight hair, blue/green eyes, freckles etc. my result I was neither a redhead nor a blonde and had curly hair. Also stated I had high blood pressure, but I have always had low blood pressure. I guess DNA testing is in the early states so hopefully it will improve. As I have the raw data I did some research and found different snps that gave red hair and straight hair that were not being used in the DNA test, Very interesting subject and lots of free information on the web once you have the raw data.

My mom is a retired nurse. When she was a nursing student, her very first patient was a teenager with Huntington's Disease who was part of a study at NIH. He was already displaying symptoms of the disease, knew he was going to die, and was willing to let scientists study him in hopes that they might learn something to save future generations with the disease. It was the first time my mom realized how you strong you have to be a medical professional, because she couldn't break down and cry around a young man only a few years younger than her as his body broke down and died.

I took a GeneSight test for medications. Found out I have a variation of CYP2D6 that is a “poor metabolizer”, making me very sensitive to CYP2D6 substrates which are most anti-depressants and opioid medications. It saved me the grief of experiencing adverse side effects and finding medications that would be good for me. Genetic testing is the future of personalized medicine.

@Sciencerely 5 лет назад

As a stem cell scientist, I really appreciate the advances in life sciences in the early 21st century! For instance, DNA sequencing costs decreased over 180 000-fold over the last 15 years! Currently, there is also an international project which aims to characterise the total gene expression of each cell type (!) in the human body! We sometimes acquire huge datasets in single experiments and, although this often makes work a lot more challenging, we finally get closer and closer in grasping the concepts of life!

@Sciencerely 5 лет назад

@Prowler Cam I am not entirely sure to which of my points your response belongs to. To sequence an entire human genome, you currently have to pay around 500 bucks (which of course is not cheap). However, some years ago these costs were over 1 billion dollars and they are still expected to fall. The gene expression project is fundamentally an open database, every scientist can contribute by sharing his data. The goal is, for example, to be able to compare which genes are expressed in healthy cells over time vs. tumour cells. As a consequence, we could develop new cancer therapies (which are also probably expensive, but some health systems cover the costs - and this issue is more a political than a scientific concern).

@GANTZ90 5 лет назад

The SNP test point was huge and yet such a small portion of this video. The huge difference in information you can get between these tests is critical to understanding their limitations. As sequencing becomes easier to access this will be less of a problem. Also explaining the methods that tests like 23andMe use, by reading their white papers, would really demonstrate how these conclusions are less genetic and more association by similarities.

@Kalevala87 5 лет назад

The trouble with mental health conditions such as depression is that the diagnostic categories themselves may not be valid. So, it doesn't really matter how many hundreds of thousands of samples you have in your genome-wide association study - if you're looking across different conditions that only happen to have some behavioural symptoms in common, you're not going to find any actual gene variants in common.

I would really like to see a scishow video on the ethical/privacy concerns with different genetic companies. I've heard from acquaintances in the insurance field that companies are looking towards genetics in the future. And I believe 23andme hooked up with GSK for medication. There are so many benefits to large DNA samples, but there are also many risks. I feel like you should at the very least add a warning to consider buying life insurance *before* getting a test like this if Huntington's Disease or a similar disease is moderately likely to show up...

@limiv5272 5 лет назад

I really liked the video, except for the last part about the ways to test for genes, you could've done much better. The important thing to know, is that most commercial genetic tests do NOT sequence your genome. Instead, they use a different method that basically allows them to only check for the presence of DNA sequences they are looking for, and the number of those is limited. Therefore, if the company you use doesn't check for a mutation you have, or you have a rare or new mutation, they won't find it. If, on the other hand, you get your entire genome sequenced, then you can check for everything known to human kind, and in the future when new discoveries are made you can go back to the data and look for new things. Of course, that costs a lot more...

One huge problem I see in some of the current research from the major testing companies has to do with how they collect some of the data. I had the test done and then filled out a self-report on my health and mental state. One question that struck me was about sleeping habits. There are a lot of reasons why a person might not be sleeping well, but this only asked how many hours you sleep or if you sleep through the night. Then later there was a 'report' about how my genes relate to this sleep. I'm not a scientist, but even I can see problems with studies based only on self reports like this.

It's true there are a lot of genes that can lead to neuro-atypicality and many of these lead to depression directly (OCD being associated with low serotonin levels for instance) but what your video doesn't completely take into account is that your genes are not in a vacuum - the more people in a family that get tested, the more likely *any* genetic condition can be narrowed down, helping doctors plan better for *all* the carriers.

@fernandoaleman607 5 лет назад

I hope you talk about the necessity of diploid genome sequencing to unravel the genetic component of complex phenotypes. Right now we are mostly using short reads of DNA and that does not allow us if the read sequence correspond to your "mom" chromosome or your "dad" chromosome. Therefore we don't know the physical connection between SNPs (same chromosome or the other chromosome), because the results we get are just one long string of DNA (when we have two).

Are you wanting to keep the density the same, or increase it to handle the weight? Okay, are you only wanting to increase the length of just this one bone, or are you wanting to do the same on the other bone? Keep in mind that your arms share a similar lay out, so we have to make sure we are only effecting the bones in your legs you requested. Are you wanting to also increase your tendon length, and thickness? Are you wanting to make sure the sockets still match up properly, and are cushioned properly? Now the muscles are going to be the same as before, so you may not have enough muscle to move these new limbs. Would you like to increase them as well? Etc... for all the other areas needing to be altered to ensure the proper effect is given.

Before you submit to testing, I would encourage you to sign up for insurance. Long term care insurance, life insurance, health insurance. Any insurance that you can buy and keep for a lifetime regardless of life circumstances, so you're covered at a reasonable rate, just in case you come up positive. I would also only do testing thru a doctor. Many private companies are entitled to your dna if you purchase a test. Who knows if they'll eventually sell it to insurance companies or what. But most importantly, you should decide for yourself if you want to know. I might consider heavily reflecting on how your life would change if you found out you were positive and whether living in the unknown would be a better feeling for you. Best wishes!

@starkeclipse 4 года назад

There are different kinds of diabetes, but I believe you're thinking of Diabetes Mellitus Type 2. The following explanation isn't 100% accurate, but it's a good way to begin making sense of things: If we are all born able to process the same amount of sugar during our life before our insulin-producing organ wears out, then people who eat twice as much sugar will wear their organ out twice as fast. When the organ starts to wear out, it doesn't work as well. That's when people begin to need pills to control the sugar in their blood. Eventually the organ fails completely. Those people will then need to inject insulin directly into their body in order to use the sugar they eat. Does that kind of help?

At 5 feet tall, I am the oldest and shortest of my siblings, who range from 5'8"--my sister--to brothers, five of them, from 6 ft to 6'7". I have a grandma who was shorter than I. Genetics, even if they cant find it. (Yep, I got cheated.)

Ancestrydna seems to not test for Sickle Cell Anemia...

@Lazerblade95 5 лет назад

the way they use heritability in this seems wrong. e.g. a 20% heritabilty means that 20% of the observed variance in a population is due to genetics, not 20% of the risk comes from genetics.

My wife is a genetic counselor. If anyone is thinking about completing genetic testing and has questions about the limitations and technology behind the test, please reach out and ask. That’s what they do! To find a counselor go to www.nsgc.org

4:24 I think what you meant there (or should have meant) is that those 60-80% also include the epigenetics, which is also determined by the environment, so genes themselves just serve as a database. 60-80% is just too high of a percentage for genes themselves to control our development. There's actually plenty of studies showing the opposite - that environment directs the transcription of genes more than the "default setting" of the body, such as chronic stress, which can cause growth delays and even complete stops in child growth, for example in kids from abusive families or war zones (psychogenic dwarfism). The fascinating thing about that is, if you take out the cause of the chronic stress, the growth resumes, and vice-versa. With this last example I am referring to Robert Sapolsky's work called "Why don't Zebras get Ulcers". Still, in the end, it really comes down to how we define genes and assign values to them. P. S. This video came out right on time because I just did my DNA test, so thank you for a butterfly effect : )
