Is CLVS2 p.Pro151Ala (c.451C>G) pathogenic?

CLVS2 p.Pro151Ala (c.451C>G) is classified Uncertain significance in CLVS2 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-06-12). AlphaMissense: likely benign (0.1033); Very rare (popmax 0.00268%, afr).

How common is CLVS2 p.Pro151Ala (c.451C>G) in the general population?

CLVS2 p.Pro151Ala (c.451C>G) is very rare (popmax 0.00268%, afr) (gnomAD).

What do computational predictors say about CLVS2 p.Pro151Ala (c.451C>G)?

AlphaMissense predicts likely benign (score 0.1033) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.1033	likely benign
REVEL	0.438	indeterminate
SaProt	LLR -2.81	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL makes no 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.
