|<span class="blue-text">EXAMPLE:</span> ''ABL1''||<span class="blue-text">EXAMPLE:</span> ''BCR::ABL1''||<span class="blue-text">EXAMPLE:</span> The pathogenic derivative is the der(22) resulting in fusion of 5’ BCR and 3’ABL1.||<span class="blue-text">EXAMPLE:</span> t(9;22)(q34;q11.2)

|<span class="blue-text">EXAMPLE:</span> D, P, T
|<span class="blue-text">EXAMPLE:</span> Yes (WHO, NCCN)
|<span class="blue-text">EXAMPLE:</span>
The t(9;22) is diagnostic of CML in the appropriate morphology and clinical context (add reference). This fusion is responsive to targeted therapy such as Imatinib (Gleevec) (add reference). BCR::ABL1 is generally favorable in CML (add reference).
|-
|<span class="blue-text">EXAMPLE:</span> ''CIC''
|<span class="blue-text">EXAMPLE:</span> ''CIC::DUX4''
|<span class="blue-text">EXAMPLE:</span> Typically, the last exon of ''CIC'' is fused to ''DUX4''. The fusion breakpoint in ''CIC'' is usually intra-exonic and removes an inhibitory sequence, upregulating ''PEA3'' genes downstream of ''CIC'' including ''ETV1'', ''ETV4'', and ''ETV5''.
|<span class="blue-text">EXAMPLE:</span> t(4;19)(q25;q13)
|<span class="blue-text">EXAMPLE:</span> Common (CIC-rearranged sarcoma)
|<span class="blue-text">EXAMPLE:</span> D
|
|<span class="blue-text">EXAMPLE:</span>
''DUX4'' has many homologous genes; an alternate translocation in a minority of cases is t(10;19), but this is usually indistinguishable from t(4;19) by short-read sequencing (add references).
|-
|<span class="blue-text">EXAMPLE:</span> ''ALK''
|<span class="blue-text">EXAMPLE:</span> ''ELM4::ALK''
Other fusion partners include ''KIF5B, NPM1, STRN, TFG, TPM3, CLTC, KLC1''
|<span class="blue-text">EXAMPLE:</span> Fusions result in constitutive activation of the ''ALK'' tyrosine kinase. The most common ''ALK'' fusion is ''EML4::ALK'', with breakpoints in intron 19 of ''ALK''. At the transcript level, a variable (5’) partner gene is fused to 3’ ''ALK'' at exon 20. Rarely, ''ALK'' fusions contain exon 19 due to breakpoints in intron 18.

|<span class="blue-text">EXAMPLE:</span> Rare (Lung adenocarcinoma)
|<span class="blue-text">EXAMPLE:</span> T

Both balanced and unbalanced forms are observed by FISH (add references).

|<span class="blue-text">EXAMPLE:</span> ''ABL1''
|<span class="blue-text">EXAMPLE:</span> N/A
|<span class="blue-text">EXAMPLE:</span> Intragenic deletion of exons 2–7 in ''EGFR'' removes the ligand-binding domain, resulting in a constitutively active tyrosine kinase with downstream activation of multiple oncogenic pathways.
