| Missense predictors do not apply to this variant type; conservation/SpliceAI carries the signal. | ||

| SpliceAI | Δ0.79 | donor loss · deltas |
| Pangolin | Δ0.76 | loss · gain 0.09 · agrees with SpliceAI · independent |

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.
