Endometrial cancer is a complex disease influenced by both somatic and germline mutations. While individual mutations in genes such as , and members of the DNA mismatch repair (MMR) system have been extensively studied, comprehensive analyses comparing somatic and germline mutations within the same cohort are limited. This study compares these mutations using whole exome sequencing (WES) data from tumor and blood samples in patients with endometrial cancer. Thirteen female patients with histologically confirmed endometrial cancer were selected. Tumor tissues and matched blood samples were collected and subjected to WES at the CeGaT laboratory, followed by bioinformatics analysis and annotation using the Geneyx platform. WES revealed significant somatic and germline DNA mutations, with key pathogenic variants identified in genes such as , and . Comparative analysis showed distinct and overlapping mutation profiles, highlighting the importance of integrating somatic and germline data in endometrial cancer research.
