For AP Bio’s Genetics and Health Symposium, Veronica Zehnder and I researched and taught about Huntington’s Disease using the platform VoiceThread. This was such a humbling and informative project, and I encourage you to check it out here!

Dr Annaliese amd Veronica, great job on this VT. I like the medium! First, a minor criticism: Anni, you often use the word “um”. You should refrain from using that word as it detracts from your presence and presentation. Second, the good: wow! Great presentation and breakdown of the information. This is a huge subject area, and you give the listener all that infor Ina very approachable and user friendly layperson format and medium. I especially like the breakout of the disease’s genetic components and how they related to the very real world consequences of a very small CAG error in one parent and how that translates to is offspring. The repeat expansion was an eye opener for me. I really connected the dots about how the disease progresses and accelerates in patients. I never knew that, and I venture that most people would think the same without seeing your research. I assume we have our DNA and it remains static. This repeat expansion illustrates the opposite. Amazing! I also found that even though an HD carrier can pass on the trait, a person may also get the disease or trait via a new mutation. Wow. That is truly sobering. I think under the genetic testing slide, you could clear up the ambiguity I have for the testing for HD during pregnancy. You state that testing can be performed in the 11th week of the pregnancy. Does that mean that week 11 is the earliest time, the only time or up until that time? One last question, I know you state that HD affect one in 10k American, but how many of those are children? And I know you mention the Caucasian versus Asian probabilities, but are there population under those categories that higher prevalence rates of the disease? Are they environmentally triggered? Great job on this. I really enjoyed learning about this subject in this medium. Thank you.
