Computational evidence

Protein change
AlphaMissense	0.1989	likely benign
REVEL	0.288	benign-leaning
SaProt	LLR -8.23	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.
Splicing

Conservation	phyloP 11	GERP 2.9, phastCons 1
Regional constraint	o/e 0.90	unconstrained · MANE · 121 kb · p 0.032 · regional, not allelic
Overall
CADD	25.4	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 0.00119% European (non-Finnish) · 14/1,180,034 alleles

Filtering AF 0.000688% ClinGen BA1/BS1 input FAF95, joint · FAF99 0.000539%

Overall 0.000867% 14/1,614,048 alleles · very rare exomes 12/1,461,876 · genomes 2/152,172 · 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.
