Computational evidence
| Protein change | ||
| Missense predictors do not apply to this variant type; conservation carries the signal. | ||
| Consequence | frameshift | predicted loss-of-function in a LoF-intolerant gene |
|---|---|---|
| NMD | escapes | premature termination codon in the last exon (14 of 14) — the truncated protein is likely expressed. PVS1 input, not an applied code |
| Splicing | ||
| SpliceAI | — | not assessed · substitutions only |
| Constraint at this position | ||
| Conservation | phyloP 7.9 | GERP 2.8, phastCons 1 |
Predicted loss-of-function is descriptive, not an applied PVS1 code.
