Is AIRE p.Val443Met (c.1327G>A) pathogenic?

AIRE p.Val443Met (c.1327G>A) is classified Likely benign in AIRE (ClinVar, Single submitter, 2 submitters; last evaluated 2026-01-09). AlphaMissense: likely benign (0.1573); Ultra-rare (popmax 0.0534%, amr); Associated with autoimmune polyendocrine syndrome type 1.

What condition is associated with AIRE p.Val443Met (c.1327G>A)?

AIRE p.Val443Met (c.1327G>A) is associated with autoimmune polyendocrine syndrome type 1 (ClinVar).

How common is AIRE p.Val443Met (c.1327G>A) in the general population?

AIRE p.Val443Met (c.1327G>A) is ultra-rare (popmax 0.0534%, amr) (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.Val443Met (c.1327G>A)?

AlphaMissense predicts likely benign (score 0.1573) — an in-silico prediction, not a clinical call.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
