Is MEN1 p.Pro71Ala (c.211C>G) pathogenic?

MEN1 p.Pro71Ala (c.211C>G) is classified Uncertain significance in MEN1 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-02-16). AlphaMissense: likely benign (0.0691); Absent from gnomAD v4.1; Associated with multiple endocrine neoplasia type 1.

What condition is associated with MEN1 p.Pro71Ala (c.211C>G)?

MEN1 p.Pro71Ala (c.211C>G) is associated with multiple endocrine neoplasia type 1 (ClinVar).

How common is MEN1 p.Pro71Ala (c.211C>G) in the general population?

MEN1 p.Pro71Ala (c.211C>G) 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.Pro71Ala (c.211C>G)?

AlphaMissense predicts likely benign (score 0.0691) — an in-silico prediction, not a clinical call.
