Is ECE2 p.Pro210Ser (c.628C>T) pathogenic?

ECE2 p.Pro210Ser (c.628C>T) is classified Uncertain significance in ECE2 (ClinVar, Single submitter, 1 submitter; last evaluated 2021-08-12). AlphaMissense: likely benign (0.0861); Ultra-rare (popmax 0.0296%, sas).

How common is ECE2 p.Pro210Ser (c.628C>T) in the general population?

ECE2 p.Pro210Ser (c.628C>T) is ultra-rare (popmax 0.0296%, sas) (gnomAD).

What do computational predictors say about ECE2 p.Pro210Ser (c.628C>T)?

AlphaMissense predicts likely benign (score 0.0861) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0861	likely benign
REVEL	0.045	moderately benign-leaning
SaProt	LLR -4.67	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.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM P256S vs ClinVar P210S) — verify the residue.

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.
