Is AIP p.Asn264= (c.792C>T) pathogenic?

AIP p.Asn264= (c.792C>T) is classified Likely benign in AIP (ClinVar, Multiple submitters, 3 submitters; last evaluated 2026-01-12). Ultra-rare (popmax 0.0384%, sas); Associated with growth hormone secreting pituitary adenoma 1.

What condition is associated with AIP p.Asn264= (c.792C>T)?

AIP p.Asn264= (c.792C>T) is associated with growth hormone secreting pituitary adenoma 1, Cushing disease due to pituitary adenoma, hereditary neoplastic syndrome (ClinVar).

How common is AIP p.Asn264= (c.792C>T) in the general population?

AIP p.Asn264= (c.792C>T) is ultra-rare (popmax 0.0384%, sas) (gnomAD).

How is Familial isolated pituitary adenoma inherited?

Typically Autosomal dominant (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.
