Computational evidence

Protein change
AlphaMissense	0.1075	likely benign
REVEL	0.198	benign-leaning
SaProt	LLR -7.79	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know
Constraint at this position
Conservation	phyloP 5.8	GERP -0.32, phastCons 0.96
Regional constraint	o/e 0.96	unconstrained · MANE · 21 kb · p 0.12 · regional, not allelic
Overall
CADD	20.4	PHRED · no single calibrated threshold — expert panels disagree

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.

Population frequency

gnomAD v4.1 · exomes + genomes

Grpmax group 8.48e-05% European (non-Finnish) · 1/1,179,248 alleles

Overall 6.22e-05% 1/1,608,076 alleles · very rare exomes 0/1,455,844 · genomes 1/152,232 · joint denominator

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.
