Is CDH1 p.Leu11Pro (c.32T>C) pathogenic?

CDH1 p.Leu11Pro (c.32T>C) is classified Uncertain significance in CDH1 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-04-01). AlphaMissense: likely benign (0.214); Absent from gnomAD v4.1; Associated with hereditary diffuse gastric adenocarcinoma.

What condition is associated with CDH1 p.Leu11Pro (c.32T>C)?

CDH1 p.Leu11Pro (c.32T>C) is associated with hereditary diffuse gastric adenocarcinoma (ClinVar).

How common is CDH1 p.Leu11Pro (c.32T>C) in the general population?

CDH1 p.Leu11Pro (c.32T>C) is absent from gnomAD v4.1 (gnomAD).

How is Hereditary diffuse gastric cancer inherited?

Typically Autosomal dominant (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about CDH1 p.Leu11Pro (c.32T>C)?

AlphaMissense predicts likely benign (score 0.214) — an in-silico prediction, not a clinical call.
