Computational evidence
| Protein change | ||
| Missense predictors do not apply to this variant type; conservation/SpliceAI carries the signal. | ||
| Consequence | nonsense (stop-gain) | predicted loss-of-function |
|---|---|---|
| NMD | predicted | premature termination codon in exon 8 of 16 |
| Splicing | ||
| SpliceAI | Δ0.22 | donor loss · deltas |
| Pangolin | Δ0.34 | loss · gain 0.01 · agrees with SpliceAI · independent |
| Constraint at this position | ||
| Conservation | phyloP 4.8 | GERP 0.83, phastCons 0.68 |
| Overall | ||
| CADD | 37.0 | 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.
