How common is ADARB2 p.Val576Met (c.1726G>A) in the general population?

ADARB2 p.Val576Met (c.1726G>A) is very rare (popmax 0.00573%, amr) (gnomAD).

What do computational predictors say about ADARB2 p.Val576Met (c.1726G>A)?

AlphaMissense predicts likely benign (score 0.12) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.12	likely benign
REVEL	0.527	indeterminate
SaProt	LLR -8.23	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.
