How common is DUSP6 p.Ser174Cys (c.521C>G) in the general population?

DUSP6 p.Ser174Cys (c.521C>G) is very rare (popmax 0.00833%, amr) (gnomAD).

What do computational predictors say about DUSP6 p.Ser174Cys (c.521C>G)?

AlphaMissense predicts likely benign (score 0.1587) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1587	likely benign
REVEL	0.35	indeterminate
SaProt	LLR -9.14	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL makes no 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.

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.
