Protein change
AlphaMissense	0.9747	likely pathogenic · top 1% in BRCA2
REVEL	0.865	moderately pathogenic-leaning
⇒ AlphaMissense and REVEL both call this damaging.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — a triage signal, not a reclassification

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