"Genetics and Down Syndrome: What You Need to Know About Epigenetics"
Manage episode 480790192 series 3653322
đ Episode Snapshot:
This episode explores epigeneticsâhow factors like nutrition, stress, and sleep can influence how genes are expressed without changing the DNA itself. For individuals with Down syndrome, this matters deeply. While the extra chromosome in Trisomy 21 affects gene activity, we can use functional medicine to help modulate that activity and support better outcomes.
đ§Ź Genetics vs. EpigeneticsâA Quick Primer
- Genetics: Your DNA is like a cookbook. Each gene is a recipe passed down from your parents.
- Epigenetics: Influences which recipes are used and how oftenâaffected by things like diet, stress, sleep, and toxins.
Why it matters in DS:
Genes arenât destiny. Epigenetics gives us tools to help offset common challenges like inflammation, cognitive delays, and accelerated aging.
đ Down Syndrome & Epigenetic Challenges
- Trisomy 21 = 47 chromosomes, ~300 extra genes
- Impaired DNA methylation affects detox, cognition, and cellular repair
- Overactive genes on chromosome 21 can drive inflammation, oxidative stress, and cognitive changes
- Examples: DYRK1A, RCAN1, SOD1, APP, CBS, IFNAR1/2
đ§ How Functional Medicine Helps
A personalized, root-cause approach can support healthy gene expression:
- Nutrients: B12, folate, choline, zinc
- Antioxidants: Glutathione, NAC, vitamins C & E
- Anti-inflammatory foods: omega-3s, Mediterranean-style diet
- Detox & lifestyle: reduce toxins, improve sleep, manage stress
đ Takeaways for Parents
- Focus on what you can changeâfood, environment, daily habits
- Small steps can shift gene expression in powerful ways
- Work with a provider trained in functional or integrative medicine
đĄ Q&A Highlights
Can you âturn offâ a gene? Yesâepigenetics acts like a dimmer switch.
Are changes permanent? Not to your DNA, but some effects can last long-term.
Too late to start? Neverâitâs always the right time to support your childâs health.
đŹ Final Thoughts
Genes load the gun. Environment pulls the trigger.
You have more influence than you thinkâand you donât have to do it alone.
