Is ESS2 p.Asn272Ser (c.815A>G) pathogenic?

ESS2 p.Asn272Ser (c.815A>G) is classified Uncertain significance in ESS2 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-10-16). AlphaMissense: likely benign (0.1735); Very rare (popmax 0.00519%, amr).

How common is ESS2 p.Asn272Ser (c.815A>G) in the general population?

ESS2 p.Asn272Ser (c.815A>G) is very rare (popmax 0.00519%, amr) (gnomAD).

What do computational predictors say about ESS2 p.Asn272Ser (c.815A>G)?

AlphaMissense predicts likely benign (score 0.1735) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1735	likely benign
REVEL	0.271	benign-leaning
SaProt	LLR -5.12	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.
