In most of these tumors, the t(2;5)(p23;q35) translocation causes fusion of the ALK gene to the 5' region of the nucleophosmin (NPM) gene, but other different ALK partners have been identified, including nonmuscle tropomyosin (TPM3), TRK-fused gene (TFG), 5' aminoimidazole-4-carboxamide ribonucleotide formyltranferase/IMP cyclohydrolase (ATIC), clathrin heavy chain gene (CLTC), and moesin (MSN).
