Is CCL8 p.Pro78Ser (c.232C>T) pathogenic?

CCL8 p.Pro78Ser (c.232C>T) is classified Uncertain significance in CCL8 (ClinVar, Single submitter, 1 submitter; last evaluated 2021-09-17). AlphaMissense: ambiguous (0.393); Ultra-rare (popmax 0.0749%, afr).

How common is CCL8 p.Pro78Ser (c.232C>T) in the general population?

CCL8 p.Pro78Ser (c.232C>T) is ultra-rare (popmax 0.0749%, afr) (gnomAD).

What do computational predictors say about CCL8 p.Pro78Ser (c.232C>T)?

AlphaMissense predicts ambiguous (score 0.393) — an in-silico prediction, not a clinical call.

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.
