Analysis of the Ovarian Serous Cystadenocarcinoma dataset (TCGA, n = 579) revealed that chromosomal cytoband 12p13.33, which comprises the WNK1 gene, was among the top‐ranked altered genomic locations (Figure 2A), reaching statistical significance (p = 8.7e−07). This evidence concerns the gene WNK1 and ovarian serous cystadenocarcinoma.
