Is AIP p.Glu245Lys (c.733G>A) pathogenic?

AIP p.Glu245Lys (c.733G>A) is classified Conflicting classifications of pathogenicity in AIP (ClinVar, Conflicting submitters, 6 submitters; last evaluated 2026-01-20). AlphaMissense: likely benign (0.0752); Ultra-rare (popmax 0.0453%, afr); Associated with growth hormone secreting pituitary adenoma 1.

What condition is associated with AIP p.Glu245Lys (c.733G>A)?

AIP p.Glu245Lys (c.733G>A) is associated with growth hormone secreting pituitary adenoma 1, hereditary neoplastic syndrome (ClinVar).

How common is AIP p.Glu245Lys (c.733G>A) in the general population?

AIP p.Glu245Lys (c.733G>A) is ultra-rare (popmax 0.0453%, afr) (gnomAD).

How is Familial isolated pituitary adenoma inherited?

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

What do computational predictors say about AIP p.Glu245Lys (c.733G>A)?

AlphaMissense predicts likely benign (score 0.0752) — 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.
