Protein change
AlphaMissense	0.9845	likely pathogenic · top 7% in CELSR3
REVEL	0.961	strongly 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.
