UNC5D and uterine cancer: As a newly characterized tumor suppressor gene, UNC5D was recently reported to be mutated in non-small-cell lung cancer, uterine cancer and stomach cancer in a public dataset from The Cancer Genome Atlas (TCGA); however, the TCGA analysis of PTC implied that somatic mutations targeting UNC5D are uncommon in PTC, which was consistent with data from the Catalogue of Somatic Mutations in Cancer (COSMIC) database.
