Is DYRK2 p.Ala9Val (c.26C>T) pathogenic?

DYRK2 p.Ala9Val (c.26C>T) is classified Uncertain significance in DYRK2 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-02-08). AlphaMissense: likely benign (0.166); Very rare (popmax 0.00169%, nfe).

How common is DYRK2 p.Ala9Val (c.26C>T) in the general population?

DYRK2 p.Ala9Val (c.26C>T) is very rare (popmax 0.00169%, nfe) (gnomAD).

What do computational predictors say about DYRK2 p.Ala9Val (c.26C>T)?

AlphaMissense predicts likely benign (score 0.166) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.166	likely benign
REVEL	0.064	moderately benign-leaning
SaProt	LLR -7.12	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.
