e13106Background: Genetic predisposition to uterine serous carcinoma (USC) remains unclear and has been related to Lynch Syndrome (LS) and BRCA1/2 mutations. Wide NGS panels for this condition are starting to be implemented and data remain scarce. Methods: Consecutive USC were identified from a prospective endometrial cancer database (ECD) in a single institution. Clinical information including stage, follow-up, a three-generation pedigree, Microsatellite Instability (MSI) with 8 markers and the Mismatch Repair Protein (MMRPro) staining status, was retrieved from the ECD. Germline genetic testing was performed using a commercially available NGS panel including 80 familial cancer genes (Onco-GeneSGKit) on a MiSeq sequencer. Pathogenic or likely pathogenic variants were confirmed by Sanger sequencing. Results: Twenty-one women out of a total of 150 (14%) cases contained in the ECD were diagnosed with a USC. Median age was 65 (40-84 yo), median Body Mass Index of 26 (19-40), and histologically 18 were define...
