What condition is associated with EDAR p.Ala174Val (c.521C>T)?

EDAR p.Ala174Val (c.521C>T) is associated with Inborn genetic diseases (ClinVar).

How common is EDAR p.Ala174Val (c.521C>T) in the general population?

EDAR p.Ala174Val (c.521C>T) is very rare (popmax 0.00094%, nfe) (gnomAD).

What do computational predictors say about EDAR p.Ala174Val (c.521C>T)?

AlphaMissense predicts likely benign (score 0.074) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.074	likely benign
REVEL	0.241	benign-leaning
SaProt	LLR -6.11	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.

Population frequency

Grpmax group 0.00094% European (non-Finnish) · 11/1,169,946 alleles

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.
