Computational evidence

Protein change
AlphaMissense	0.0845	likely benign
REVEL	0.147	moderately benign-leaning
SaProt	LLR -7.13	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know
Constraint at this position
Conservation	phyloP 5	GERP 2.1, phastCons 0.97
Regional constraint	o/e 1.11	unconstrained · MANE · 1,930 bp · p 0.0028 · regional, not allelic
Overall
CADD	11.53	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.
