| AlphaMissense | 0.0635 | likely benign |

| REVEL | 0.051 | moderately benign-leaning |
| SaProt | LLR -6.11 | tolerated |

| CADD | 0.1 | PHRED · no single calibrated threshold — expert panels disagree |
ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification
AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.
