Hi Zenovia,
We categorize all nonsense and frameshift mutations as truncating. Splice mutations are those that are predicted to alter the splicing of a gene, and SVs are structural variants, typically larger rearrangements on the genomic level, which sometimes lead to gene fusions.
I hope this is helpful.
Keep in mind that all variants observed in this gene and variants of unknown significance, meaning there is no evidence yet that any of them contribute to tumor development, spread, or sensitivity to therapy.
Niki.
