ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL is an independent agreement signal.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM A631V vs ClinVar A494V) — verify the residue.
