Protein change
AlphaMissense	0.0875	likely benign
REVEL	0.078	moderately benign-leaning
⇒ AlphaMissense and REVEL both call this tolerated.

Regional constraint	o/e 0.90	unconstrained · MANE · 18 kb · p 0.012 · regional, not allelic
Overall
CADD	21.4	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.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM P2417S vs ClinVar P2291S) — verify the residue.

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.
