Protein change
AlphaMissense	0.2131	likely benign
REVEL	0.101	moderately benign-leaning
SaProt	LLR -3.60	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

No allele count reported in gnomAD v4.1 (AN 1,237,412). This is missing data, not an absence: the variant may or may not be present in gnomAD. Rarity (ACMG PM2) and BA1/BS1 cannot be assessed for it.
