I have identified 12 transcript variants of my gene of interest from ensembl and I want to find the expression of these transcripts in body tissues using GTEx. I think to do this however, I need to have the rs number for the transcript variants. I was wondering if anyone can suggest the best way to go about finding this information out as I am struggling?
You can get this information from the NCBI.

You are confusing alternative splicing with mutation. You need to be precise. Do you want to see base changes or different isoforms. The first can be identified with dbSNP (rs) and the later with ensmbl transcript ID (ENST)
I would also say that you are confusing concepts, in GTEx you will find eQTLs or sQTLs in which the presence of an SNP (rs) is correlated with the expression of a gene (eQTL) or with the expression of the isoforms of a gene (sQTLs). Therefore, if you have the Ensembl ID of the transcripts of a gene and you want to compare it with the GTEx database, you will possibly get the SNP that is correlated with it. I don't know if I made myself clear.
