Is ERMARD p.Ala291Thr (c.871G>A) pathogenic?

ERMARD p.Ala291Thr (c.871G>A) is classified Uncertain significance in ERMARD (ClinVar, Single submitter, 1 submitter; last evaluated 2025-12-08). AlphaMissense: likely benign (0.0886); Ultra-rare (popmax 0.033%, mid).

How common is ERMARD p.Ala291Thr (c.871G>A) in the general population?

ERMARD p.Ala291Thr (c.871G>A) is ultra-rare (popmax 0.033%, mid) (gnomAD).

What do computational predictors say about ERMARD p.Ala291Thr (c.871G>A)?

AlphaMissense predicts likely benign (score 0.0886) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0886	likely benign
REVEL	0.016	strongly benign-leaning
SaProt	LLR -4.35	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.
