Due to the rarity of this lymphoma the data in recurrent chromosomal rearrangement is extremely scant. There have been chromosomal rearrangements reported in association with the aggressive NK-cell leukaemia, however, none of them are considered specific for the disease. | Due to the rarity of this lymphoma the data in recurrent chromosomal rearrangement is extremely scant.

Mutations in the ''JAK-STAT'' pathway appear to be mutually exclusive.<ref name=":3" /> Most ''STAT3'' and ''STAT5B'' mutations localized to exons 20 and 21 encoding the Src homology 2 (SH2) domain, which causes ''STAT'' dimerization. Other mutations identified: 9p copy gains (containing ''JAK2),'' point mutation in protein tyrosine phosphatase (''PTPRK'') (tumor suppressor that negatively regulates ''STAT3''). mutations in ''PTPN4'' and ''PTPN23.<ref name=":2" /><ref name=":7" />'' | Mutations in the ''JAK-STAT'' pathway appear to be mutually exclusive.<ref name=":3" /> Most ''STAT3'' and ''STAT5B'' mutations localized to exons 20 and 21 encoding the Src homology 2 (SH2) domain, which causes ''STAT'' dimerization.

Molecular abnormalities present possible therapeutic implications. Dufva et al identified high sensitivity of ANKL cell lines to JAK and BCL2 inhibition. Other possibly effective drug classes are heat shock protein 90 (HSP90) inhibitors, polo-like kinase (PLK) inhibitors, aurora kinase (AURK) inhibitors, cyclin-dependent kinase inhibitors, and histone deacetylase inhibitors.<ref name=":6" /> | Molecular abnormalities present possible therapeutic implications.
