I'm really new if the field and maybe my question is a little bit naive.
I'm trying to annotate my SNPs by using VEP. The reason to do this is to find the nonsense SNPs on each genome, the synonymous and non-Synonymous. The organism that I'm working on is sheep. The thing that is a little bit confusing to me is the tag system that Ensembl uses. For example, the "synonymous_variant" is for the synonymous SNPs, but I'm not so sure about the non-synonymous and the nonsense. I'm taking the "coding_sequence_variant" and "stop_gained", respectively. Am I right? Also, I cannot identify the CNVs. Is there any particular tag for this?
A second issue that I faced is that for some gene IDs there is no information about the name of the gene (symbol tag). Is there any way to use somehow a list with these IDs and find the names of these genes?
Thank you very much in advance and I'm really sorry for the questions "bombing".
