Is CHMP5 p.Ile192Val (c.574A>G) pathogenic?

CHMP5 p.Ile192Val (c.574A>G) is classified Uncertain significance in CHMP5 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-04-09). AlphaMissense: likely benign (0.0933); Ultra-rare (popmax 0.01%, amr).

How common is CHMP5 p.Ile192Val (c.574A>G) in the general population?

CHMP5 p.Ile192Val (c.574A>G) is ultra-rare (popmax 0.01%, amr) (gnomAD).

What do computational predictors say about CHMP5 p.Ile192Val (c.574A>G)?

AlphaMissense predicts likely benign (score 0.0933) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0933	likely benign
REVEL	0.108	moderately benign-leaning
SaProt	LLR -4.82	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.
