Protein change
AlphaMissense	0.8845	likely pathogenic
REVEL	0.763	pathogenic-leaning
SaProt	LLR -12.10	damaging
⇒ AlphaMissense, REVEL and SaProt all call this damaging.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know

Regional constraint	o/e 0.61	unconstrained · MANE · 6,734 bp · p 5.4e-12 · regional, not allelic
Overall
CADD	29.6	PHRED · no single calibrated threshold — expert panels disagree

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — 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.
