Computational evidence
| Protein change | ||
| Missense predictors do not apply to this variant type; conservation/SpliceAI carries the signal. | ||
| Splicing | ||
| Splice region | donor +3 | donor splice region (+3, within the first 6 intronic nt) · inside the BP7-excluded zone |
|---|---|---|
| SpliceAI | Δ0.60 | acceptor loss · deltas |
| Pangolin | Δ0.39 | loss · gain 0.01 · agrees with SpliceAI · independent |
| Constraint at this position | ||
| Conservation | phyloP 11 | GERP 2.9, phastCons 1 |
| Non-coding constraint | — | not assessed · autosomes only, so chrX has no window · absence ≠ unconstrained |
| Overall | ||
| CADD | 19.12 | PHRED · no single calibrated threshold — expert panels disagree |

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.
