How common is ARFGAP2 p.Pro167Leu (c.500C>T) in the general population?

ARFGAP2 p.Pro167Leu (c.500C>T) is very rare (popmax 0.00162%, nfe) (gnomAD).

What do computational predictors say about ARFGAP2 p.Pro167Leu (c.500C>T)?

AlphaMissense predicts likely benign (score 0.0651) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0651	likely benign
REVEL	0.022	moderately benign-leaning
SaProt	LLR -9.04	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.
