Is MEN1 p.Ala467Asp (c.1400C>A) pathogenic?

MEN1 p.Ala467Asp (c.1400C>A) is classified Uncertain significance in MEN1 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-05-23). AlphaMissense: likely benign (0.1272); Absent from gnomAD v4.1; Associated with multiple endocrine neoplasia type 1.

What condition is associated with MEN1 p.Ala467Asp (c.1400C>A)?

MEN1 p.Ala467Asp (c.1400C>A) is associated with multiple endocrine neoplasia type 1, hereditary neoplastic syndrome (ClinVar).

How common is MEN1 p.Ala467Asp (c.1400C>A) in the general population?

MEN1 p.Ala467Asp (c.1400C>A) is absent from gnomAD v4.1 (gnomAD).

How is Multiple endocrine neoplasia type 1 inherited?

Typically Autosomal dominant, Not applicable (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about MEN1 p.Ala467Asp (c.1400C>A)?

AlphaMissense predicts likely benign (score 0.1272) — an in-silico prediction, not a clinical call.

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

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM A472D vs ClinVar A467D) — verify the residue.
