Huntington's Disease: The Science of a genetic disorder

- Huntington’s disease is a terrible degenerative disorder that robs you of your memories, your movement and eventually your life, but in this video I want to look at the science of this inherited condition.
Located on the short p arm of chromosome 4 is the HTT gene. This gene codes for a protein called huntingtin, so what is the role of this protein. Well it isn’t fully understood exactly what this protein does, but it looks like it has a number of different functions within cells, so let’s have a look at those.
Huntingtin is involved in cell transport and also keeping cells alive. The gene for the normal huntingtin protein has a region near to the beginning which consists of the same 3 bases repeated multiple times. These bases are CAG, and this codes for the amino acid glutamine. In a person with Huntinton’s disease, the huntingtin protein is shaped wrong so it can’t do it’s normal job. In addition the wrongly shaped protein damages the cells over time. Below I’ve put some links to Huntington’s support organisations.

I've watched a bunch of other videos that talk about HD and THIS is what I've been searching for this whole time. Exact cellular mechanism. thank you so much for this!!! very well done video that honestly deserves a lot more views than what it has.
Thank you so much for this video. HD is a terrible disease that gets very little exposure is popular media.
Unfortunately, my family has had a lot of experience with it as it killed both my Father in 2009 and my younger Brother in 2014.
Your channel is fantastic and I hope it goes from strength to strength.
I'm so sorry to hear that.
I feel you stay strong I watched a bunch of people in my family die from it now I got diagnosed at 23. My younger cousin just died from it, I just pray my kids don't have it
This channel is so underrated. The video quality and voiceovers are great. Really bring future ahead. Keep going mate!
Love your videos on genetic diseases ❤
You should have also mentioned that Huntington's is a dominnt genetic disorder, which is not normally the case for gentetic disorders. Meaning f you have it, there's a 50% chnce you'll pass it on, and therefore should definitely not have children.
Also in the rare scenario some ends up HH as appose to Hh (h = normal recessive, H = infected dominant), those people don't tend to live very long t all.
I used to think that. I understand. These days, admittedly, I have a small nursing bias. Regardless. I was uncomfortable with a "50%" & "Never have children." Personally I don't believe in limits. They're just fun hurdles. & Who doesn't like to play?🙏🏼 The odds are 50/50 in your favour if you have a good smile.
Well that way to late to say people definitely shouldn't have children.. that's not your choice to make.. do you have Huntington disease?
Thank goodness for scientists as you can still have children, and children whom are HD free.
Wow! This video was awesome and complex at the same time. Cell production is so complicated. I'm amazed that we're able to cure any disease considering what's actually going in in these cells. On another note. Is this your most complex 3d modelling to date? Those protein molecule along within the animation look complex.
Great job.
Thank you very much. Medicine is such a fascinating subject. I think it probably was my most complex model, though to be honest there is a way of using protein models from the protein database (yes such a cool thing exists). Also fortunately dynein moves in quite a simplistic way. I dread having to model the movement of kinesin
Documentaries about severe diseases showing cellular processes are some sort of horror films. Seeing proteins interfere with other proteins, knowing it's about those diseases, is strangely frightening.
I love you biology videos! However when I was watching your A level biology series, one day it vanished from the face of your channel, what happened to it? And would there be more bio content to come?
Scarier than any horror movie. Great video though
okay i wanted to make miraculous fanmade kwami when im older but is this desease or any others like CJD of fatal insomnia comes around then ima tell god to cure prions in heaven
😂😂 your god created it.. 🙄🙄
