Computational evidence
| Protein change | ||
| AlphaMissense | 0.0873 | likely benign |

| REVEL | 0.174 | moderately benign-leaning |
| SaProt | LLR -5.95 | tolerated |

| Conservation | phyloP 4.4 | GERP 1.5, phastCons 1 |
| Regional constraint | o/e 0.84 | unconstrained · MANE · 1,787 bp · p 0.003 · regional, not allelic |
| Overall | ||
| CADD | 21.1 | 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.
