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 organs. This accumulation leads to oxidative stress, inflammation, and ultimately, tissue damage. The disease is caused by mutations in the ATP7B gene, which plays a crucial role in copper transport and excretion.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of Wilson's disease. In Wilson's disease, the ATP7B protein is dysfunctional, leading to impaired copper efflux from the liver into the bile. As a result, copper accumulates in the liver, causing damage to hepatocytes and leading to liver dysfunction. The excess copper is then transported to other organs, including the brain, where it can cause neurological symptoms.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because Wilson's disease is not caused by a deficiency of copper in the diet. In fact, patients with Wilson's disease often have elevated copper levels in their bodies.
* **Option B:** This option is incorrect because Wilson's disease is not primarily a disorder of iron metabolism. While iron and copper are both essential trace elements, Wilson's disease is specifically related to copper accumulation.
* **Option C:** This option is incorrect because Wilson's disease is not primarily a disorder of zinc metabolism. While zinc and copper are both essential trace elements, Wilson's disease is specifically related to copper accumulation.
**Clinical Pearl / High-Yield Fact**
It's essential to note that Wilson's disease can present with a wide range of symptoms, including liver disease, neurological symptoms, and psychiatric symptoms. A key diagnostic feature is the presence of Kayser-Fleischer rings, which are due to copper deposition in the cornea.
