Is ERN2 p.His33Tyr (c.97C>T) pathogenic?

ERN2 p.His33Tyr (c.97C>T) is classified Uncertain significance in ERN2 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-02-02). AlphaMissense: likely benign (0.0904); Absent from gnomAD v4.1.

How common is ERN2 p.His33Tyr (c.97C>T) in the general population?

ERN2 p.His33Tyr (c.97C>T) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about ERN2 p.His33Tyr (c.97C>T)?

AlphaMissense predicts likely benign (score 0.0904) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0904	likely benign
REVEL	0.081	moderately benign-leaning
SaProt	LLR -8.18	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.
