Recently, fusions involving TNC have rarely been documented to occur in other neoplasms, including TNC-NRG1 fusion in a non-small cell lung carcinoma [19] and in a papillary renal cell carcinoma [20], and TNC-USP6 fusion in a primary aneurysmal bone cyst [21]. The gene discussed is TNC; the disease is non-small cell lung carcinoma.
