Computational evidence

Protein change
AlphaMissense	0.0885	likely benign
REVEL	0.195	benign-leaning
⇒ AlphaMissense and REVEL both call this tolerated.

Regional constraint	o/e 0.92	unconstrained · MANE · 4,360 bp · p 0.0017 · regional, not allelic
Overall
CADD	19.83	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.

Population frequency

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.
