Gene Symbol CDH1
Synonyms Arc-1 | BCDS1 | CD324 | CDHE | ECAD | LCAM | UVO
Gene Description CDH1, cadherin 1, type 1, encodes E-Cadherin and is a tumor suppressor (PMID: 30562755) involved in epithelial cell-cell adhesion, cell signaling, differentiation, and polarity (PMID: 18726070, PMID: 26674224). CDH1 germline mutations are associated with hereditary diffuse gastric cancer (PMID: 30562755) and somatic mutations are found in gastric, breast, colon, and NSCLC cancers (PMID: 27283171, PMID: 25184143).

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

CDH1 over exp pancreatic ductal adenocarcinoma sensitive Erlotinib + Selumetinib Phase II Actionable In a Phase II clinical trial, patients with pancreatic ductal adenocarcinoma tumors expressing high levels of Cdh1 were more likely to respond to a combination therapy of Tarceva (erlotinib) and Selumetinib (AZD6244) (PMID: 26251290). 26251290
CDH1 over exp lung non-small cell carcinoma resistant BI2536 Preclinical Actionable In a preclinical study, non-small cell lung carcinoma cells over expressing CDH1 were resistant to BI2536 in culture (PMID: 26597303). 26597303
CDH1 over exp lung non-small cell carcinoma resistant Volasertib Preclinical Actionable In a preclinical study, non-small cell lung carcinoma cells over expressing CDH1 were resistant to volasertib in culture (PMID: 26597303). 26597303
CDH1 R63* ERBB2 L869Q breast cancer predicted - sensitive Capecitabine + Lapatinib Case Reports/Case Series Actionable In a clinical case study, treatment with the combination of Tykerb (lapatinib) and Xeloda (capecitabine) resulted in prolonged response and reduction in liver metastasis in a metastatic breast cancer patient harboring ERBB2 L869Q and CDH1 R63* mutations (PMID: 26487584). 26487584
