Abstract：
Rearrangements of RET are drivers of oncogenesis, traceable in different cancer types as papillary thyroid carcinoma (PTC), non-small cell lung cancer, colorectal or breast cancer. Anchored multiplex PCR based next-generation sequencing (NGS) can detect RET rearrangements involving previously unknown partner genes.
A sample of PTC underwent NGS, following detection of RET rearrangement by fluorescence in situ hybridization. Expression analysis of ANKRD26 and RET was performed for the tumor harboring ANKRD26-RET, for corresponding normal thyroid tissue and PTC tumors with representative genetic alterations (BRAFV600E, CCDC6-RET), complemented by a comparative search in the \"UniProt\" database.
NGS analysis resulted in the discovery of the fusion ANKRD26-RET. ANKRD26 mRNA was expressed in all PTC tumors (ANKRD26-RET, BRAFV600E, CCDC6-RET) and in normal thyroid tissue, whereas RET mRNA was detected only in the tumors with RET rearrangement. On protein level, ANKRD26-RET combines the RET tyrosine kinase to ankyrin repeat and coiled-coil domains.
ANKRD26-RET is a novel rearrangement of the RET gene, associated with RET expression in thyroid tissue. The result is a fusion of the RET tyrosine kinase to prominent protein-protein interaction motifs. Further studies are required to investigate the influence of different RET rearrangements on metastasis and disease-free survival in PTC.
