Computational evidence

Protein change
AlphaMissense	0.1777	likely benign
REVEL	0.313	indeterminate
SaProt	LLR -6.05	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL is indeterminate.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know
Constraint at this position
Conservation	phyloP 8.5	GERP 0.37, phastCons 1
Regional constraint	o/e 0.94	unconstrained · MANE · 50 kb · p 0.065 · regional, not allelic
Overall
CADD	26.3	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.
