Protein change
AlphaMissense	0.9976	likely pathogenic · top 1% in CEP57
REVEL	0.403	indeterminate
SaProt	LLR -12.74	damaging
⇒ AlphaMissense and SaProt both call this damaging; REVEL 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 and SaProt are independent agreement signals.
