**Why the Correct Answer is Right:**
Sickle cell anemia is a genetic disorder caused by a single gene mutation, specifically the homozygous state of the β-globin chain gene mutation resulting in production of HbS. The disease affects individuals from various ethnic backgrounds, not just African Americans.

**Why Each Wrong Option is Incorrect:**

A. False: Sickle cell anemia affects individuals from various ethnic backgrounds, not just African Americans.
B. False: Sickle cell anemia is a common and serious condition that significantly impacts a patient's quality of life, leading to various complications.
C. False: Sickle cell anemia causes severe symptoms and complications, including pain crises, organ damage, and potential life-threatening complications.
D. False: Sickle cell anemia is a life-threatening emergency that requires immediate medical attention due to its severe symptoms and complications.

**Clinical Pearl:** Understanding the correct answer and reasons for incorrect options is crucial for diagnosing and managing patients with sickle cell anemia effectively. This knowledge empowers healthcare professionals to provide appropriate care and support for patients affected by this genetic disorder, which affects millions of individuals globally.
