How did you search by co-ordinate? I am familiar with most operations in NCBI and UCSC Genome Browser, but ensembl is not my cup of tea :(

FWIW, UCSC genome browser shows Ensembl transcripts overlapping with the SNP rs4821700

Hello,

Your questions in my opinion is simple to answer perhaps. The problem so to say of ensembl is that the database comprise all the variant of all the transcripts associated with the genome. I think that your problem can be solved simple searching what of these transcripts is the original transcripts. what this means? that you can click on the transcript that have the same aa length of your protein. for example if your protein have 346 aa. you'll have the original transcripts of the same length.

I have searched for your snp id and my result is this

This is the map of variation in which you can search the location

I hope that the links are useful
