Clinics and Pathology


Only one case to date, an 18-month-old boy with a null-ALCL (Meech et al., 2001).


Cells expressed both myeloid (CD13, CD33, HLA-DR) and natural killer (CD3-/CD56+, germline TCR genes, CD25+/CD122+/granzyme B+) cell antigens.


The patient was in remission 14 months after completion of therapy.

Genes Involved and Proteins

Gene name
ALK (anaplastic lymphoma receptor tyrosine kinase)
Protein description
1620 amino acids; ALK is a membrane associated tyrosine kinase receptor of the insulin receptor superfamily.
Gene name
TPM4 (tropomyosin)
Protein description
248 amino acids; tropomyosins are actin-binding proteins; component of cytoskeletal microfilaments; role in the calcium dependent regulation of striated muscle.

Result of the Chromosomal Anomaly


5TPM4-3ALK. Fusion between TPM4 nucleotide 714 and ALK nucleotide 4084.
