Protein change
AlphaMissense	0.998	likely pathogenic ✓ concordant with ClinVar
REVEL	0.925	moderately pathogenic-leaning
SaProt	LLR -12.10	damaging
⇒ AlphaMissense, REVEL and SaProt all call this damaging.

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

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM R47K vs ClinVar R36K) — 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.
