Thsi article is a list of common cytogenetic tests. An introduction to cytogenetics is in the cytogenetics article.
Karyotyping
Findings:
- 5q deletion seen in myelodysplastic syndromes.[1]
- Y deletion in MDS[2] - relatively common in old men.
ISH
Cytogenetic tests at one hospital:[3]
| Test | Parameters | Notes |
|---|---|---|
| BCR/ABL1 | CML or ALL | Tx: imatinib |
| MLL[4] | ALL or AML | rearrangment --> marker of poor prognosis[5] |
| MYC | Burkitt's lymphoma + others | prognostic |
| ALK | DLBCL - BCL6, BCL2 or MYC | ? |
| MALT1 | MALT lymphoma | trisomy 3, trisomy 18 |
| CCND1 | mantle cell lymphoma | ? |
| BCL2 | follicular lymphoma | t(14;18)(q32;q21)[6] |
| ERBB2 (HER2) | breast cancer | prognostic, Tx (trastuzumab) |
| EWSR1 | small round blue cell tumour (suspected Ewing sarcoma) |
