Is AIRE p.Arg328= (c.984G>A) pathogenic?

AIRE p.Arg328= (c.984G>A) is classified Likely benign in AIRE (ClinVar, Single submitter, 1 submitter; last evaluated 2024-12-02). Very rare (popmax 8.48e-05%, nfe); Associated with autoimmune polyendocrine syndrome type 1.

What condition is associated with AIRE p.Arg328= (c.984G>A)?

AIRE p.Arg328= (c.984G>A) is associated with autoimmune polyendocrine syndrome type 1 (ClinVar).

How common is AIRE p.Arg328= (c.984G>A) in the general population?

AIRE p.Arg328= (c.984G>A) is very rare (popmax 8.48e-05%, nfe) (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.
