Is BMP1 p.Ala489Val (c.1466C>T) pathogenic?

BMP1 p.Ala489Val (c.1466C>T) is classified Uncertain significance in BMP1 (ClinVar, Single submitter, 1 submitter; last evaluated 2019-08-19). AlphaMissense: likely benign (0.2832); Very rare (popmax 0.000339%, nfe).

How common is BMP1 p.Ala489Val (c.1466C>T) in the general population?

BMP1 p.Ala489Val (c.1466C>T) is very rare (popmax 0.000339%, nfe) (gnomAD).

What do computational predictors say about BMP1 p.Ala489Val (c.1466C>T)?

AlphaMissense predicts likely benign (score 0.2832) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.2832	likely benign
REVEL	0.224	benign-leaning
SaProt	LLR -9.76	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know

Regional constraint	o/e 0.84	unconstrained · MANE · 35 kb · p 1e-07 · regional, not allelic
Overall
CADD	25.7	PHRED · no single calibrated threshold — expert panels disagree

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.
