Is AIP p.Ile4Val (c.10A>G) pathogenic?

AIP p.Ile4Val (c.10A>G) is classified Uncertain significance in AIP (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-10-25). AlphaMissense: likely benign (0.0711); Ultra-rare (popmax 0.0165%, mid); Associated with hereditary neoplastic syndrome.

What condition is associated with AIP p.Ile4Val (c.10A>G)?

AIP p.Ile4Val (c.10A>G) is associated with hereditary neoplastic syndrome (ClinVar).

How common is AIP p.Ile4Val (c.10A>G) in the general population?

AIP p.Ile4Val (c.10A>G) is ultra-rare (popmax 0.0165%, mid) (gnomAD).

What do computational predictors say about AIP p.Ile4Val (c.10A>G)?

AlphaMissense predicts likely benign (score 0.0711) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.
