Is COMMD5 p.Ser19Asn (c.56G>A) pathogenic?

COMMD5 p.Ser19Asn (c.56G>A) is classified Uncertain significance in COMMD5 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-08-20). AlphaMissense: likely benign (0.1189); Ultra-rare (popmax 0.0373%, afr).

How common is COMMD5 p.Ser19Asn (c.56G>A) in the general population?

COMMD5 p.Ser19Asn (c.56G>A) is ultra-rare (popmax 0.0373%, afr) (gnomAD).

What do computational predictors say about COMMD5 p.Ser19Asn (c.56G>A)?

AlphaMissense predicts likely benign (score 0.1189) — 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.
