**Core Concept**
Renal Cell Carcinoma (RCC), also known as Hypernephroma, is a type of kidney cancer that originates in the lining of the proximal convoluted tubule, a part of the small tubes in the kidney that transport waste molecules from the blood to the urine. It is the most common type of kidney cancer in adults.

**Why the Correct Answer is Right**
RCC is typically a sporadic tumor, but 2-3% of cases are associated with von Hippel-Lindau (VHL) disease, a genetic disorder that predisposes individuals to develop multiple types of tumors, including RCC. The VHL gene acts as a tumor suppressor, and mutations in this gene lead to the formation of RCC. The most common histological subtype of RCC is clear cell RCC, which accounts for approximately 75% of cases.

**Why Each Wrong Option is Incorrect**
**Option A:** RCC often presents with hematuria, flank pain, or a palpable abdominal mass. While this statement is true, it is not the focus of the question, so we cannot evaluate its correctness here.
**Option B:** The most common histological subtype of RCC is clear cell RCC. This statement is true.
**Option C:** RCC is typically a sporadic tumor, but 2-3% of cases are associated with von Hippel-Lindau (VHL) disease. This statement is true.
**Option D:** RCC is often associated with a mutation in the VHL gene, which acts as a tumor suppressor. This statement is true.

**Clinical Pearl / High-Yield Fact**
It is essential for clinicians to be aware of the association between RCC and VHL disease, as individuals with VHL disease require regular screening for RCC.

**Correct Answer:** D. RCC is not often associated with a mutation in the VHL gene, but rather, the VHL gene acts as a tumor suppressor and mutations in this gene lead to the formation of RCC.
