Computational evidence

Protein change
AlphaMissense	0.0817	likely benign
REVEL	0.054	moderately benign-leaning
SaProt	LLR -7.84	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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

gnomAD v4.1 · exomes + genomes

Grpmax group 8.76e-05% European (non-Finnish) · 1/1,141,350 alleles

Overall 7.26e-05% 1/1,377,418 alleles · very rare

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.
