What condition is associated with ELN p.Ala458Gly (c.1373C>G)?

ELN p.Ala458Gly (c.1373C>G) is associated with supravalvular aortic stenosis (ClinVar).

How common is ELN p.Ala458Gly (c.1373C>G) in the general population?

ELN p.Ala458Gly (c.1373C>G) is very rare (popmax 0.000424%, nfe) (gnomAD).

What do computational predictors say about ELN p.Ala458Gly (c.1373C>G)?

AlphaMissense predicts likely benign (score 0.2783) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.2783	likely benign
REVEL	0.217	benign-leaning
SaProt	LLR -8.60	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 A487G vs ClinVar A458G) — verify the residue.

Population frequency

Grpmax group 0.000424% European (non-Finnish) · 5/1,180,016 alleles

Overall 0.000342% 5/1,461,626 alleles · very rare

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.
