What condition is associated with AIRE p.Asp478= (c.1434C>T)?

AIRE p.Asp478= (c.1434C>T) is associated with autoimmune polyendocrine syndrome type 1 (ClinVar).

How common is AIRE p.Asp478= (c.1434C>T) in the general population?

AIRE p.Asp478= (c.1434C>T) is ultra-rare (popmax 0.0263%, sas) (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.
