What condition is associated with CDH1 p.Asp313Val (c.938A>T)?

CDH1 p.Asp313Val (c.938A>T) is associated with hereditary diffuse gastric adenocarcinoma, hereditary neoplastic syndrome (ClinVar).

How common is CDH1 p.Asp313Val (c.938A>T) in the general population?

CDH1 p.Asp313Val (c.938A>T) 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.Asp313Val (c.938A>T)?

AlphaMissense predicts likely benign (score 0.1187) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.
