Protein change
AlphaMissense	0.849	likely pathogenic ✓ concordant with ClinVar
REVEL	0.371	indeterminate
SaProt	LLR -13.00	damaging
⇒ AlphaMissense and SaProt both call this damaging; REVEL is indeterminate.

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

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM N101S vs ClinVar N88S) — verify the residue.
