Is BRD10 p.Pro21Ala (c.61C>G) pathogenic?

BRD10 p.Pro21Ala (c.61C>G) is classified Uncertain significance in BRD10 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-12-15). AlphaMissense: likely benign (0.0547); Ultra-rare (popmax 0.0148%, afr).

How common is BRD10 p.Pro21Ala (c.61C>G) in the general population?

BRD10 p.Pro21Ala (c.61C>G) is ultra-rare (popmax 0.0148%, afr) (gnomAD).

What do computational predictors say about BRD10 p.Pro21Ala (c.61C>G)?

AlphaMissense predicts likely benign (score 0.0547) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0547	likely benign
REVEL	0.046	moderately benign-leaning
SaProt	LLR -5.28	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.

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.
