Low expression of E-Cadherin and variants associated with diffuse gastric cancer.

Background: Reduced or null expression of E-cadherin protein is a frequent cause of diffuse gastric cancer (DGC). More than 50% of patients with DGC present somatic variants in gene.

Objectives: The objectives of this study were to study E-cadherin expression and identify variants in the gene in gastric tumors of patients with DGC.

Predicting Pathogenicity of CDH1 Gene Variants in Patients with Early-onset Diffuse Gastric Cancer from Western Mexico.

Background: Early-onset diffuse gastric cancer (EODGC) occurs at or before 50 years of age. Pathogenic mutations and germline deletions in the CDH1 gene (E-cadherin) are well-documented genetic factors associated with the causes of EODGC.

Objective: The objective of the study was to study CDH1 germline variants and their potential functional impact in patients with EODGC in a Mexican population.
