AlphaMissense	0.9965	likely pathogenic · top 8% in HERC1
REVEL	0.741	pathogenic-leaning
SaProt	—	not scored · why
⇒ AlphaMissense and REVEL both call this damaging; SaProt makes no call.

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

AlphaMissense carries the ACMG weight for missense; REVEL is an independent agreement signal.
