Protein change

SaProt	LLR -5.34	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

Regional constraint	o/e 1.08	unconstrained · MANE · 75 kb · p 0.42 · regional, not allelic
Overall
CADD	22.0	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 N649S vs ClinVar N704S) — verify the residue.

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.
