False about Dubin – Johnson syndrome
**Core Concept**
Dubin-Johnson syndrome is a rare **genetic disorder** characterized by an inability to secrete conjugated bilirubin into the bile, resulting in a form of **chronic jaundice**. This condition is due to a mutation in the **ABCC2 gene**, which codes for a protein involved in the transport of bilirubin glucuronides.
**Why the Correct Answer is Right**
Since the correct answer option is not provided, let's discuss the general pathophysiology. The syndrome leads to the accumulation of **epinephrine metabolites** and **bilirubin** in the liver, causing **black liver** appearance. The **ABCC2 protein** plays a crucial role in the transport of conjugated bilirubin into the bile canaliculi.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option text, it's challenging to provide a detailed explanation. However, any option stating that Dubin-Johnson syndrome is related to **unconjugated bilirubin** would be incorrect, as the condition involves **conjugated bilirubin**.
**Option B:** Similarly, without the text, we can't provide a direct explanation. But if an option suggests the condition is **acquired**, it would be incorrect, as Dubin-Johnson syndrome is **inherited**.
**Option C:** Again, lacking the specific text, but if it implies the condition affects **bilirubin uptake** into hepatocytes, it would be incorrect, as the issue lies in the **secretion of conjugated bilirubin** into the bile.
**Option D:** Without the text, we can't directly address this option. However, any statement contradicting the **genetic basis** or **pathophysiological mechanism** of Dubin-Johnson syndrome would be incorrect.
**Clinical Pearl / High-Yield Fact**
Dubin-Johnson syndrome is a **benign condition** with no significant morbidity or mortality, but it can be a diagnostic challenge. Recognizing the **characteristic black liver** and understanding the **genetic basis** can aid in diagnosis.
**Correct Answer:** Not provided in the query.
