One demonstrated the absence of identifiable fusion transcripts in 19/22 CCSKs (two tumors demonstrated the YWHAE-NUTM2 fusion transcript previously described, and a single tumor with a TERT-IRX2 fusion transcript was identified resulting in abnormal TERT overexpression driven by high IRX2 expression identified in all CCSKs) [14]. The gene discussed is IRX2; the disease is neoplasm.
