Protein change
AlphaMissense	0.8469	likely pathogenic · top 6% in CFAP69
REVEL	0.18	moderately benign-leaning
SaProt	LLR -5.31	tolerated
⇒ AlphaMissense calls this damaging; REVEL and SaProt do not.

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.
