**Core Concept**
The chromosomal translocation t(2,8) involves a reciprocal exchange of genetic material between chromosomes 2 and 8. This specific translocation is associated with a particular type of leukemia characterized by the uncontrolled proliferation of malignant cells.

**Why the Correct Answer is Right**
The t(2,8) translocation is characteristically seen in mantle cell lymphoma, a type of B-cell non-Hodgkin lymphoma. This translocation results in the overexpression of cyclin D1 due to the juxtaposition of the cyclin D1 gene (CCND1) on chromosome 11 with the immunoglobulin heavy chain locus on chromosome 14, but in the case of t(2,8), the CCND1 gene is fused with the immunoglobulin heavy chain locus on chromosome 2, leading to the overexpression of cyclin D1 and subsequent uncontrolled cell proliferation.

**Why Each Wrong Option is Incorrect**
**Option A:** Not directly associated with the t(2,8) translocation.
**Option B:** Although B-cell lymphomas are often associated with chromosomal translocations, the t(2,8) translocation is specific to mantle cell lymphoma.
**Option C:** Not a correct association with the t(2,8) translocation.

**Clinical Pearl / High-Yield Fact**
Mantle cell lymphoma is a distinct entity within B-cell non-Hodgkin lymphomas, characterized by the t(11,14) translocation in most cases, but the t(2,8) translocation is a less common variant that also leads to overexpression of cyclin D1.

**Correct Answer:** C.
