True about wilson’s disease –
**Core Concept**
Wilson's disease is a rare genetic disorder characterized by excessive accumulation of copper in the body, particularly in the liver, brain, and other vital organs. This accumulation leads to damage and dysfunction of these organs, resulting in a range of clinical manifestations. The disease is caused by mutations in the ATP7B gene, which plays a crucial role in regulating copper transport and metabolism.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of Wilson's disease. In Wilson's disease, the ATP7B gene is mutated, leading to impaired copper transport and accumulation in the liver and other organs. This accumulation causes oxidative stress, inflammation, and damage to liver cells, eventually leading to liver dysfunction and cirrhosis. The ATP7B protein is involved in the transport of copper from the liver to the bile, and its mutation impairs this process, resulting in copper accumulation.
**Why Each Wrong Option is Incorrect**
**Option A:** Not relevant to Wilson's disease.
**Option B:** Not accurate, as Wilson's disease is caused by mutations in the ATP7B gene, not by a deficiency of copper in the diet.
**Option C:** Not correct, as Wilson's disease is characterized by excessive accumulation of copper, not iron.
**Clinical Pearl / High-Yield Fact**
Wilson's disease is a classic example of a genetic disorder that can mimic other liver and neurological conditions, making it essential for clinicians to consider this diagnosis in patients with unexplained liver dysfunction or neurological symptoms, especially in young individuals.
