Is CCL8 p.Pro31Ala (c.91C>G) pathogenic?

CCL8 p.Pro31Ala (c.91C>G) is classified Uncertain significance in CCL8 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-02-28). AlphaMissense: likely benign (0.2045); Very rare (popmax 0.00267%, afr).

How common is CCL8 p.Pro31Ala (c.91C>G) in the general population?

CCL8 p.Pro31Ala (c.91C>G) is very rare (popmax 0.00267%, afr) (gnomAD).

What do computational predictors say about CCL8 p.Pro31Ala (c.91C>G)?

AlphaMissense predicts likely benign (score 0.2045) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.2045	likely benign
REVEL	0.183	benign-leaning
SaProt	LLR -11.27	damaging
⇒ SaProt calls this damaging; AlphaMissense and REVEL do not.

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.
