AlphaMissense	0.0712	likely benign
REVEL	0.11	moderately benign-leaning
⇒ AlphaMissense and REVEL both call this tolerated.

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

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM K827R vs ClinVar K701R) — 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.
