Krijgen mijn kinderen ook MS? (een diepe duik in erfelijkheid en genetica)

My sister, my father, and I all have MS. Simplified patient information doesn't reassure me about the risk for my children. Everywhere I found the same answer: "The risk is slightly elevated, but still small. About one in twenty." That's true — but it doesn't tell the whole story. And if I don't understand something, I can't be reassured by it. So I spent more than half a year diving deep into the subject. In this video I explain how heredity in MS really works — from Mendel's pea plants to HLA types, from twin studies to modern genetic research. ⏱️ 56 minutes — that's a long watch. Feel free to pause, grab a cup of coffee, or come back tomorrow for the next chapter.
