3 Figure 2 The most frequent rearranged during transfection proto-oncogene gene (RET) rearrangements: kinesin family member 5B gene (KIF5B)-RET (seven variants), coiled-coil domain containing 6 (CCDC6)-RET, nuclear receptor coactivator 4 (NCOA4)-RET, and tripartite motif containing 33 (TRIM33)-RET. E, exon; TM, transmembrane domain.

5 Figure 4 Rearranged during transfection proto-oncogene gene (RET) rearrangements by fluorescence in situ hybridization (FISH) analysis (break-apart assay; ZytoLight SPEC RET dual Color Break Apart Probe, Zytovision, CliniSciences, Nanterre, France) in two patients with lung adenocarcinoma. (A) One or two native alleles (N) and a rearranged allele (R) are present. The green spots (probe 3′ RET) and the red spots (probe 5′ RET) are split, revealing a rearrangement of the RET gene. The short distance between the two parts of the probe suggests a rearrangement with kinesin family member 5B gene (KIF5B) on the chromosome 10p. (B) A different pattern of RET rearrangement, with one or two native alleles (N), loss of the 5′ end (red signal) of the RET gene, and concomitant duplication of the derivative chromosome (R).
