Whole-exome and targeted sequencing of plasmacytoid bladder cancer, an aggressive histologic variant with a high risk of disease-specific mortality. This dataset contains summary data visualizations and sequencing data of 34 plasmacytoid-variant (signet ring cell) tumors of the bladder from 31 patients. Clinical data includes detailed cancer type, mutation count, information about mutated genes, patient...

In this study, six plasmacytoid bladder cancers were analyzed by whole exome sequencing. The results show loss of the CDH1 gene in every sample and correlate with E-cadherin loss of expression by immunohistochemistry. A separate validation cohort of plasmacytoid samples showed loss of E-cadherin expression by CDH1 mutation or promoter hypermethylation. The data includes information about the study,...
