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 +2 | canonical splice dinucleotide (donor +2) · inside the BP7-excluded zone |
| SpliceAI | Δ1.00 | donor loss · deltas |
| Pangolin | Δ0.90 | loss · gain 0.84 · agrees with SpliceAI · independent |
| Constraint at this position | ||
| Conservation | phyloP 9.4 | GERP 1.6, phastCons 1 |
| Non-coding constraint | Z 1.59 | 1 kb window · o/e 0.88 · regional · uncalibrated |

| CADD | 35.0 | PHRED · no single calibrated threshold — expert panels disagree |
Predicted loss-of-function is descriptive, not an applied PVS1 code.

gnomAD v4.1 · exomes + genomes
Absent from gnomAD v4.1. Not observed in any sequenced alleles — a rarity signal (ACMG PM2-supporting), not evidence of pathogenicity on its own.
