The institutional review board approved the consent procedure. Because these variants are spread over the entire gene, their detection requires sequencing of all 16 exons. Computational algorithms were used to predict their pathogenicity, but the results were discordant among the prediction tools. Gastric cancer: adding glycosylation to the equation. ClinVar: public archive of relationships among sequence variation and human phenotype. Some clinical studies have demonstrated an association of variant c. Predicting deleterious amino acid substitutions. These calcium-binding motifs are functionally important, because the presence of calcium ions stabilizes the active conformation of the protein. Around different deleterious variants and 29 unclassified variants of CDH1 have been reported to date [ 12 ]. In conclusion, unequivocal pathogenic germline CDH1 variants did not contribute significantly for EOGC predisposition in our cohort and the assessment of the potential pathogenicity of missense variants still represents a major challenge.

Pathogenic germline variants in CDH1 have been associated with hereditary diffuse gastric cancer (HDGC, MIM# ), an autosomal.
The N residue has already been described as one of the most important sites of E-cadherin N -glycosylation and its dependent cell-cell adhesion [ 12 ].
