How common is CABP4 p.Pro67Leu (c.200C>T) in the general population?

CABP4 p.Pro67Leu (c.200C>T) is ultra-rare (popmax 0.0144%, sas) (gnomAD).

What do computational predictors say about CABP4 p.Pro67Leu (c.200C>T)?

AlphaMissense predicts likely benign (score 0.067) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.067	likely benign
REVEL	0.053	moderately benign-leaning
SaProt	LLR -8.21	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.
