Is BCAM p.Ala233Ser (c.697G>T) pathogenic?

BCAM p.Ala233Ser (c.697G>T) is classified Uncertain significance in BCAM (ClinVar, Single submitter, 1 submitter; last evaluated 2025-01-21). AlphaMissense: likely benign (0.0767); Very rare (popmax 0.004%, afr).

How common is BCAM p.Ala233Ser (c.697G>T) in the general population?

BCAM p.Ala233Ser (c.697G>T) is very rare (popmax 0.004%, afr) (gnomAD).

What do computational predictors say about BCAM p.Ala233Ser (c.697G>T)?

AlphaMissense predicts likely benign (score 0.0767) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0767	likely benign
REVEL	0.168	moderately benign-leaning
SaProt	LLR -6.34	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.
