Is AIRE p.Asp297= (c.891C>T) pathogenic?

AIRE p.Asp297= (c.891C>T) is classified Likely benign in AIRE (ClinVar, Single submitter, 1 submitter; last evaluated 2026-01-27). Very rare (popmax 0.00401%, afr); Associated with autoimmune polyendocrine syndrome type 1.

What condition is associated with AIRE p.Asp297= (c.891C>T)?

AIRE p.Asp297= (c.891C>T) is associated with autoimmune polyendocrine syndrome type 1 (ClinVar).

How common is AIRE p.Asp297= (c.891C>T) in the general population?

AIRE p.Asp297= (c.891C>T) is very rare (popmax 0.00401%, afr) (gnomAD).

How is Autoimmune polyendocrinopathy type 1 inherited?

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

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.
