Computational evidence

Protein change
Missense predictors do not apply to this variant type; conservation/SpliceAI carries the signal.
Consequence	canonical splice-site (±1/±2)	predicted loss-of-function
Splicing
Splice region	donor +1	canonical splice dinucleotide (donor +1) · inside the BP7-excluded zone
SpliceAI	Δ1.00	donor loss · deltas
Pangolin	Δ0.89	loss · gain 0.03 · agrees with SpliceAI · independent
Constraint at this position
Conservation	phyloP 12	GERP 1, phastCons 1
Non-coding constraint	Z 0.86	1 kb window · o/e 0.93 · regional · uncalibrated
Overall
CADD	33.0	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 8.64e-05% European (non-Finnish) · 1/1,156,898 alleles

Overall 7e-05% 1/1,428,450 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.
