Computational evidence

Protein change
Missense predictors do not apply to this variant type; conservation/SpliceAI carries the signal.
Consequence	nonsense (stop-gain)	predicted loss-of-function
NMD	predicted	premature termination codon in exon 42 of 54
Splicing
SpliceAI	Δ0.26	acceptor loss · deltas
Pangolin	Δ0.25	loss · gain 0.01 · agrees with SpliceAI · independent
Constraint at this position
Conservation	phyloP 6	GERP 2.4, phastCons 1
Overall
CADD	45.0	PHRED · no single calibrated threshold — expert panels disagree

Predicted loss-of-function is descriptive, not an applied PVS1 code.

Population frequency

gnomAD v4.1 · exomes + genomes

Grpmax group 8.54e-05% European (non-Finnish) · 1/1,171,446 alleles

Overall 6.95e-05% 1/1,438,962 alleles · very rare

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.
