Translocation t(2:8)(p12:q24) is associated with:
**Core Concept**
The translocation t(2;8)(p12;q24) involves the juxtaposition of genetic material from chromosomes 2 and 8, specifically at the p12 and q24 regions, respectively. This chromosomal abnormality is commonly seen in certain types of lymphoma and leukemia.
**Why the Correct Answer is Right**
The correct answer is associated with Burkitt lymphoma, a type of B-cell non-Hodgkin lymphoma. This translocation leads to the overexpression of the c-MYC gene due to its proximity to the immunoglobulin heavy chain gene on chromosome 2, resulting in uncontrolled cell proliferation. The c-MYC protein plays a critical role in cell cycle regulation, and its dysregulation is central to the pathogenesis of Burkitt lymphoma.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the translocation t(2;8)(p12;q24) is not associated with follicular lymphoma, which typically involves a different genetic abnormality, such as t(14;18)(q32;q21).
* **Option B:** This option is incorrect because the translocation t(2;8)(p12;q24) is not associated with acute myeloid leukemia (AML), which often involves different genetic abnormalities, such as t(8;21)(q22;q22) or inv(16)(p13.1q22).
* **Option C:** This option is incorrect because the translocation t(2;8)(p12;q24) is not associated with chronic lymphocytic leukemia (CLL), which typically involves different genetic abnormalities, such as deletions of 13q or 17p.
**Clinical Pearl / High-Yield Fact**
The c-MYC gene is a classic example of an oncogene, a gene that, when dysregulated, can contribute to cancer development. Understanding the role of c-MYC in Burkitt lymphoma highlights the importance of genetic alterations in cancer pathogenesis.
**Correct Answer: B. Burkitt lymphoma.**
