Is CCL5 p.Ser28Leu (c.83C>T) pathogenic?

CCL5 p.Ser28Leu (c.83C>T) is classified Uncertain significance in CCL5 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-04-06). AlphaMissense: likely benign (0.2216); Ultra-rare (popmax 0.0332%, mid).

How common is CCL5 p.Ser28Leu (c.83C>T) in the general population?

CCL5 p.Ser28Leu (c.83C>T) is ultra-rare (popmax 0.0332%, mid) (gnomAD).

What do computational predictors say about CCL5 p.Ser28Leu (c.83C>T)?

AlphaMissense predicts likely benign (score 0.2216) — an in-silico prediction, not a clinical call.

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.
