The identification of rearrangements driving expression of Neurotrophic Receptor Tyrosine Kinase (NTRK) family kinases in tumours has become critically important due to the availability of effective, specific inhibitor drugs. Whole genome sequencing (WGS) combined with RNA Sequencing (RNAseq) can identify novel and recurrent expressed fusions. Here we describe three
SPECC1L
-NTRK fusions identified in two paediatric central nervous system cancers and an extracranial solid tumour using WGS and RNAseq. These fusions arose either through a simple balanced rearrangement, or in the context of a complex chromoplexy event. We cloned the
SPECC1L
-NTRK2 fusion directly from a patient sample and showed that enforced expression of this fusion is sufficient to promote cytokine-independent survival and proliferation. Cells transformed by
SPECC1L
-NTRK2 expression are sensitive to a TRK inhibitor drug. We report here that
SPECC1L
-NTRK fusions can arise in a range of paediatric cancers. Whilst WGS and RNAseq are not required to detect NTRK fusions, these techniques may be of benefit when NTRK fusions are not suspected on clinical grounds or not identified by other methods.
