Computational evidence
| Protein change | ||
| Missense predictors do not apply to this variant type; conservation carries the signal. | ||
| Consequence | frameshift | predicted loss-of-function |
|---|---|---|
| NMD | predicted | premature termination codon in exon 1 of 3 |
| Splicing | ||
| SpliceAI | — | not assessed · substitutions only |

Predicted loss-of-function is descriptive, not an applied PVS1 code.
