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

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM R3600H vs ClinVar R3463H) — 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.
