Computational evidence

Protein change
AlphaMissense	0.4296	ambiguous
REVEL	0.883	moderately pathogenic-leaning
SaProt	LLR -13.03	damaging
⇒ REVEL and SaProt both call this damaging; AlphaMissense is indeterminate.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know

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

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.
