Hi,

in the TCGA database there is a feature ,"Variant Classification", which classifies each mutation to being in the 5'UTR, 3'UTR, intron, etc...

I know they use the GRCh38 version of chromosomes and annotations. however, each gene has multiple transcripts. so if I have a position X that some transcripts indicated is in an intron and some indicate it's in an exon how do I classify it?

I could'nt find in the TCGA website a conclusive version that matches the "Variant Classification" completely and that is what I need...

Thank you.
