Computational evidence

Protein change
AlphaMissense	0.7423	likely pathogenic
REVEL	0.219	benign-leaning
SaProt	LLR -9.98	tolerated
⇒ AlphaMissense calls this damaging; REVEL and SaProt do not.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know
Constraint at this position
Conservation	phyloP 4	GERP 1.5, phastCons 1
Regional constraint	o/e 1.13	unconstrained · MANE · 20 kb · p 9.1e-08 · regional, not allelic
Overall
CADD	23.7	PHRED · no single calibrated threshold — expert panels disagree

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

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.
