Protein change
AlphaMissense	0.999	likely pathogenic · top 1% in DSP
REVEL	0.677	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.

Population frequency

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
