Is FPR3 p.Ile77Val (c.229A>G) pathogenic?

FPR3 p.Ile77Val (c.229A>G) is classified Uncertain significance in FPR3 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-09-30). AlphaMissense: likely benign (0.089); Ultra-rare (popmax 0.035%, amr).

How common is FPR3 p.Ile77Val (c.229A>G) in the general population?

FPR3 p.Ile77Val (c.229A>G) is ultra-rare (popmax 0.035%, amr) (gnomAD).

What do computational predictors say about FPR3 p.Ile77Val (c.229A>G)?

AlphaMissense predicts likely benign (score 0.089) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.089	likely benign
REVEL	0.142	moderately benign-leaning
SaProt	LLR -5.98	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.
