Computational evidence

Protein change
AlphaMissense	0.0766	likely benign
REVEL	0.038	moderately benign-leaning
⇒ AlphaMissense and REVEL both call this tolerated.

Overall
CADD	17.18	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 A1378V vs ClinVar A1252V) — 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.
