Most common translocation in burkitt’s lymphoma is:
From what I remember, Burkitt's lymphoma is associated with the MYC gene. The translocation usually involves the MYC gene on chromosome 8 with an immunoglobulin gene. The common ones are with the IgH gene on chromosome 14, but there are also others with IgK on 2 or IgL on 22. So the most common would be t(8;14)(q24;q32), which is the MYC-IGH translocation.
Wait, the options weren't provided, but the correct answer is supposed to be t(8;14). Let me make sure. The translocations in Burkitt's are t(8;14), t(8;2), and t(8;22), but the most common is definitely t(8;14). The other options might include other translocations like t(14;18) which is for follicular lymphoma, or t(9;22) for CML, or t(15;17) for APL. So the incorrect options would be those.
For the explanation, the core concept is the MYC gene translocations in Burkitt's lymphoma. The correct answer is t(8;14) because it fuses MYC with the IgH gene, leading to overexpression. The wrong options are other translocations linked to different lymphomas or leukemias. The clinical pearl is to remember the "3-8-14" translocation for Burkitt's.
Need to structure this into the required sections. Make sure each part is concise but covers the necessary details without being too long. Check for any possible mistakes, like confusing with other translocations. Also, ensure that the clinical pearl is a high-yield fact that's easy to remember for exams.
**Core Concept**
Burkitt's lymphoma is characterized by chromosomal translocations involving the **MYC gene** on chromosome 8. The most common translocation activates MYC through juxtaposition with immunoglobulin gene promoters, leading to uncontrolled proliferation.
**Why the Correct Answer is Right**
The **t(8;14)(q24;q32)** translocation fuses the MYC gene on chromosome 8 with the immunoglobulin heavy chain (IGH) locus on chromosome 14. This results in constitutive overexpression of MYC, driving rapid cell cycle progression and hallmark "starry sky" histology. Less common translocations (t(8;2) or t(8;22)) involve Igκ or Igλ light chain genes but share the same pathogenic mechanism.
**Why Each Wrong Option is Incorrect**
**Option A:** t(9;22) is the Philadelphia chromosome seen in CML and ALL, not Burkitt’s.
**Option B:** t(14;18) is characteristic of follicular lymphoma, involving BCL2 and IGH.
**Option C:** t
