Table 1 lists 74 RET fusions found in 10 tissue types in the curated set of non-redundant studies of cBioportal. Consistent with other reports[4,9,11,31-33], the intrachromosomal rearrangements[34] CCDC6-RET and NCOA4-RET occurred most often in PTC, whereas the intrachromosomal rearrangements KIF5B-RET and CCDC6-RET were the most common in lung adenocarcinoma. Here, CCDC6 is linked to lung adenocarcinoma.
