Computational evidence

Protein change
AlphaMissense	0.8782	likely pathogenic
REVEL	0.165	moderately benign-leaning
⇒ AlphaMissense calls this damaging; REVEL does not.

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

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM R298W vs ClinVar R1207W) — 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.
