Is DMBT1 p.Pro222Ser (c.664C>T) pathogenic?

DMBT1 p.Pro222Ser (c.664C>T) is classified Uncertain significance in DMBT1 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-02-09). AlphaMissense: likely benign (0.0873); Very rare (popmax 0.00134%, afr).

How common is DMBT1 p.Pro222Ser (c.664C>T) in the general population?

DMBT1 p.Pro222Ser (c.664C>T) is very rare (popmax 0.00134%, afr) (gnomAD).

What do computational predictors say about DMBT1 p.Pro222Ser (c.664C>T)?

AlphaMissense predicts likely benign (score 0.0873) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0873	likely benign
REVEL	0.013	strongly benign-leaning
SaProt	LLR -6.61	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.
