Is AGER p.Arg29Trp (c.85C>T) pathogenic?

AGER p.Arg29Trp (c.85C>T) is classified Uncertain significance in AGER (ClinVar, Single submitter, 1 submitter; last evaluated 2024-11-24). AlphaMissense: likely benign (0.1355); Very rare (popmax 0.005%, amr).

How common is AGER p.Arg29Trp (c.85C>T) in the general population?

AGER p.Arg29Trp (c.85C>T) is very rare (popmax 0.005%, amr) (gnomAD).

What do computational predictors say about AGER p.Arg29Trp (c.85C>T)?

AlphaMissense predicts likely benign (score 0.1355) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1355	likely benign
REVEL	0.227	benign-leaning
SaProt	LLR -9.46	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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.
