LRATD2 and esophageal squamous cell carcinoma: Further functional and clinical analyses strongly indicate that FAM84B (located at 8q24.13-q24.21), which is highly expressed in dysplasia and ESCC patients but not normal esophagus tissues, may contribute to oncogenesis in ESCC and that targeting FAM84B may be a promising strategy for the diagnosis of susceptibility and the early stages of ESCC.
