Causes
ALK negative ALCL is characterized by a translocation T(6;7)(p25.3;q32.3), which inactivates the DUSP22 gene and leads to a higher proliferation rate.[1] In healthy people, the product of the DUSP22 gene, the DUSP22 protein (also known as the JNK pathway-associated phosphatase or JKAP), inactivates the LCK tyrosine kinase protein during T-cell receptor signaling.[2]
DUSP22 mutations are also associated with breast cancer (the UDSMP22 protein can also block estrogen receptors)[3] and primary cutaneous ALCL.[4]
