よくある質問
What is an autosomal dominant pedigree?
It is a family diagram used to show a reported dominant pattern across generations.
Why mark unaffected relatives?
They help make the documented family pattern clear without implying a diagnosis.
Can a family tree predict Huntington disease?
No. A pedigree summarizes family history; testing and risk assessment need qualified clinical guidance.
