Protein change
AlphaMissense	0.4109	ambiguous
REVEL	0.119	moderately benign-leaning
SaProt	LLR -7.24	tolerated
⇒ REVEL and SaProt both call this tolerated; AlphaMissense is indeterminate.

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

Population frequency

gnomAD v4.1 · exomes + genomes

Grpmax group 8.69e-05% European (non-Finnish) · 1/1,150,722 alleles

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.
