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 in a haploinsufficient gene (ClinGen) |
|---|---|---|
| NMD | escapes | premature termination codon in the last exon (4 of 4) — the truncated protein is likely expressed. PVS1 input, not an applied code |
| REVEL | 0.488 | indeterminate |
| Splicing | ||
| SpliceAI | Δ0.28 | acceptor loss · deltas |
| Constraint at this position | ||
| Conservation | phyloP 7.8 | GERP 1.9, phastCons 1 |
| Overall | ||
| CADD | 37.0 | PHRED · no single calibrated threshold — expert panels disagree |
Predicted loss-of-function is descriptive, not an applied PVS1 code.

Absent from gnomAD v4.1. Not observed in any sequenced alleles — a rarity signal (ACMG PM2-supporting), not evidence of pathogenicity on its own.
