What condition is associated with AIRE p.Pro401Arg (c.1202C>G)?

AIRE p.Pro401Arg (c.1202C>G) is associated with autoimmune polyendocrine syndrome type 1 (ClinVar).

How common is AIRE p.Pro401Arg (c.1202C>G) in the general population?

AIRE p.Pro401Arg (c.1202C>G) is absent from gnomAD v4.1 (gnomAD).

How is Autoimmune polyendocrinopathy type 1 inherited?

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

What do computational predictors say about AIRE p.Pro401Arg (c.1202C>G)?

AlphaMissense predicts likely benign (score 0.1045) — an in-silico prediction, not a clinical call.
