Computational evidence
| Protein change | ||
| Missense predictors do not apply to this variant type; conservation carries the signal. | ||
| Splicing | ||
| Splice region | donor +9 | near-intronic (+9 nt from the splice site) |
|---|---|---|
| SpliceAI | — | not assessed · no allele here is in the release |
| Constraint at this position | ||
| Conservation | phyloP 2.5 | GERP -1.1, phastCons 0.62 |
| Non-coding constraint | — | not assessed · autosomes only, so chrX has no window · absence ≠ unconstrained |
| Overall | ||
| CADD | 13.96 | 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.
