How common is DECR1 p.Ser151Pro (c.451T>C) in the general population?

DECR1 p.Ser151Pro (c.451T>C) is very rare (popmax 0.00925%, eas) (gnomAD).

What do computational predictors say about DECR1 p.Ser151Pro (c.451T>C)?

AlphaMissense predicts likely pathogenic (score 0.9437) — an in-silico prediction, not a clinical call.

AlphaMissense	0.9437	likely pathogenic · top 8% in DECR1
REVEL	0.745	pathogenic-leaning
SaProt	LLR -14.52	damaging
⇒ AlphaMissense, REVEL and SaProt all call this damaging.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — 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.
