Hypermethylation of KLF9 was associated with lower survival rates in several cancer types such as LGG, thymoma (THYM), and uterine carcinosarcoma (UCS), but hypermethylation of KLF9 in KIRC was associated with a better prognosis in KIRC (Fig. S3F). This evidence concerns the gene KLF9 and uterine carcinosarcoma.
