**Core Concept**
Pheochromocytomas are rare neuroendocrine tumors arising from the adrenal medulla, often associated with hereditary syndromes. Mutations in specific genes can lead to the development of these tumors. Understanding the genetic basis of pheochromocytoma is crucial for diagnosis and management.

**Why the Correct Answer is Right**
Pheochromocytoma-associated syndromes are primarily linked to mutations in the following genes:
* **VHL (Von Hippel-Lindau)**: responsible for Von Hippel-Lindau syndrome, which increases the risk of pheochromocytoma.
* **RET**: associated with multiple endocrine neoplasia type 2A (MEN2A) and 2B (MEN2B), which can involve pheochromocytoma.
* **SDHB, SDHC, SDHD**: mutations in these genes are linked to familial pheochromocytoma and paraganglioma syndromes.

**Clinical Pearl / High-Yield Fact**
The classic triad of symptoms for pheochromocytoma includes hypertension, headaches, and palpitations. However, the diagnosis should be considered in any patient with episodic hypertension and tachycardia, even without these classic symptoms.
