Computational evidence

Protein change
AlphaMissense	0.0786	likely benign
REVEL	0.047	moderately benign-leaning
SaProt	LLR -8.14	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

Regional constraint	o/e 1.01	unconstrained · MANE · 13 kb · p 0.75 · regional, not allelic
Overall
CADD	21.7	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.
