Computational evidence
| Protein change | ||
| Missense predictors do not apply to this variant type; conservation carries the signal. | ||
| Consequence | nonsense (stop-gain) | predicted loss-of-function |
|---|---|---|
| NMD | escapes | premature termination codon within the last 50 nt of the penultimate exon (88 of 89, 37 nt from its 3' end) — the truncated protein is likely expressed. PVS1 input, not an applied code |
| Splicing | ||
| SpliceAI | <0.2 | no splice effect predicted · four deltas, not one · how we know |
| Constraint at this position | ||
| Conservation | phyloP 3.9 | GERP 1.6, phastCons 1 |
| Overall | ||
| CADD | 39.0 | 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.
