Pathology

spindle cell proliferation with myofibroblastic differenciation and an inflammatory infiltrate

Prognosis

low malignant potential and good prognosis

Genes Involved and Proteins

Gene name

ALK (anaplastic lymphoma receptor tyrosine kinase)

Location

2p23.2

Protein description

1620 amino acids; 177 kDa; glycoprotein (200 kDa mature protein) ; membrane associated tyrosine kinase receptor

Gene name

CLTC (clathrin heavy polypeptide)

Location

17q23.1

Protein description

1675 amino acids, 191 kDa; mediate endocytosis of transmembrane receptors.

Result of the chromosomal anomaly

Description

5 CLTC - 3 ALK

Description

2196 amino acids. 1634 N-term amino acid from CLTC, containing nearly all of CLTC, including the triskelion assembly domain, fused to the 562 C-term amino acids from ALK (i.e. the entire cytoplasmic portion of ALK with the tyrosine kinase domain).
