How common is CD83 p.Asp30Asn (c.88G>A) in the general population?

CD83 p.Asp30Asn (c.88G>A) is ultra-rare (popmax 0.0165%, mid) (gnomAD).

What do computational predictors say about CD83 p.Asp30Asn (c.88G>A)?

AlphaMissense predicts likely benign (score 0.1017) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1017	likely benign
REVEL	0.042	moderately benign-leaning
SaProt	LLR -7.65	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.

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.
