Computational evidence

Protein change
AlphaMissense	0.1324	likely benign
REVEL	0.323	indeterminate
SaProt	LLR -10.51	damaging
⇒ SaProt calls this damaging; AlphaMissense does not; REVEL is indeterminate.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM S776P vs ClinVar S770P) — verify the residue.

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.
