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 haploinsufficient gene (ClinGen) |
|---|---|---|
| NMD | predicted | premature termination codon in exon 68 of 79 |

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