第 33 題
有關透納氏症（Turner syndrome）的敘述，下列何者錯誤？
- A Ｘ染色體短臂上有SHOX基因，因此病患會有矮小症狀（short stature）
- B 可能有左心異常（left-heart abnormalities）
- C 因為是性染色體異常，所以有性腺發育不全（gonadal dysgenesis）
- D 智力皆不受影響，完全正常
思路引導 VIP
「當人體細胞大規模地缺失了一整條性染色體，影響了從心臟到性腺的多個系統發育時，從生理邏輯推論，你認為大腦神經的高層次認知功能，是否具備完全不受遺傳缺失干擾的『豁免權』呢？」

Hmph. You got this one right. Good. Now try lifting this. grunts, weights clank
- Pay attention!: So, Turner syndrome ($45, X$). Yeah, it's about a missing X chromosome. Keep it simple. And that $SHOX$ gene thing? Miss it, you're short. Not rocket science. About 30% get heart trouble—left heart hypoplasia or aortic coarctation. Tough break, but it happens. Most can flap their gums fine, "verbal IQ" usually checks out. But don't you dare claim they're "completely normal" in every single aspect. They often hit snags with spatial perception, non-verbal reasoning, or executive function. So, when option (D) spouts "皆不受影響、完全正常" (completely unaffected, totally normal)? That's the kind of absolute nonsense you should scoff at in medicine. Nothing's ever "perfectly" anything. wipes sweat from brow
- Not a treasure map: This question was just a simple gut check. Can you tell "generally okay" from "absolutely flawless"? And can you smell a trap disguised as an absolute statement? You did. Barely. Now, which way was the mess hall again? I need a nap. stretches, weights shift
