Abstract
Endometrial cancer is the sixth most commonly diagnosed cancer in women worldwide, causing ∼74,000 deaths annually. Serous endometrial cancers are a clinically aggressive subtype with a poorly defined genetic etiology. We used whole-exome sequencing to comprehensively search for somatic mutations within ∼22,000 protein-encoding genes in 13 primary serous endometrial tumors. We subsequently resequenced 18 genes, which were mutated in more than 1 tumor and/or were components of an enriched functional grouping, from 40 additional serous tumors. We identified high frequencies of somatic mutations in CHD4 (17%), EP300 (8%), ARID1A (6%), TSPYL2 (6%), FBXW7 (29%), SPOP (8%), MAP3K4 (6%) and ABCC9 (6%). Overall, 36.5% of serous tumors had a mutated chromatin-remodeling gene, and 35% had a mutated ubiquitin ligase complex gene, implicating frequent mutational disruption of these processes in the molecular pathogenesis of one of the deadliest forms of endometrial cancer.

The table currently shows only high value (numeric) copy number data. Copy number segments are excluded if the total copy number and minor allele values are unknown.

Sample Gene Expression Expr Level (Z-Score)

Over Expressed; Z-Score > 2.0

Under Expressed; Z-Score < -2.0

Normal; Z-Score within the range -2.0 to 2.0

CN Type Minor Allele Copy Number CN Segment Posn. Average Ploidy

1. N/A represents cases where the average ploidy value is not available( mostly ICGC samples). For some TCGA samples where the minor allele information is not available the average ploidy value could not be calculated.

2. For TCGA samples, the ASCAT algorithm was used to calculate the average ploidy.

3. For CGP samples, the PICNIC algorithm was used to calculate the average ploidy.
