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 in a LoF-intolerant gene |
|---|---|---|
| NMD | predicted | premature termination codon in exon 42 of 65 |
| Splicing | ||
| SpliceAI | <0.2 | no splice effect predicted · four deltas, not one · how we know |
| Constraint at this position | ||
| Conservation | phyloP 12 | GERP 2.1, phastCons 1 |
| Overall | ||
| CADD | 45.0 | PHRED · no single calibrated threshold — expert panels disagree |
Predicted loss-of-function is descriptive, not an applied PVS1 code.
Population frequency
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.
