Is CXCL3 p.Ala8Ser (c.22G>T) pathogenic?

CXCL3 p.Ala8Ser (c.22G>T) is classified Uncertain significance in CXCL3 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-05-06). AlphaMissense: likely benign (0.0884); Absent from gnomAD v4.1.

How common is CXCL3 p.Ala8Ser (c.22G>T) in the general population?

CXCL3 p.Ala8Ser (c.22G>T) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about CXCL3 p.Ala8Ser (c.22G>T)?

AlphaMissense predicts likely benign (score 0.0884) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0884	likely benign
REVEL	0.039	moderately benign-leaning
SaProt	LLR -6.57	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.
