Identification of a novel PARP14-TFE3 gene fusion from 10-year-old FFPE tissue by RNA-seq.

Xp11 (TFE3) translocation renal cell carcinoma (RCC) is officially recognized as a distinct subtype of RCC in the 2004 WHO classification. This neoplasm is characterized by several chromosomal translocations between the TFE3-involving Xp11.2 breakpoint and various fusion partners.

Heterogeneity of TERT promoter mutations status in squamous cell carcinomas of different anatomical sites.

Squamous cell carcinoma (SCC) can arise from different anatomical sites including the skin, head and neck, lung, esophagus, genital area, and so on. Despite the same histopathologic features and immunohistochemistry profile, the SCCs of different body sites can show tremendous differences in their presenting symptoms, risk factor associations, natural history, prognosis, and response to treatment. This may reflect the fact that SCCs are heterogenous and likely have unique molecular characteristics at different anatomical sites.
