Is ELOA p.Arg97Cys (c.289C>T) pathogenic?

ELOA p.Arg97Cys (c.289C>T) is classified Uncertain significance in ELOA (ClinVar, Single submitter, 1 submitter; last evaluated 2025-11-26). AlphaMissense: likely benign (0.1855); Very rare (popmax 0.00446%, eas).

How common is ELOA p.Arg97Cys (c.289C>T) in the general population?

ELOA p.Arg97Cys (c.289C>T) is very rare (popmax 0.00446%, eas) (gnomAD).

What do computational predictors say about ELOA p.Arg97Cys (c.289C>T)?

AlphaMissense predicts likely benign (score 0.1855) — an in-silico prediction, not a clinical call.

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 R123C vs ClinVar R97C) — 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.
