I'm working on a project where I need to reconstruct what version of a transcript was used to perform some initial analysis & annotation. I need to download the genomic coordinates for the exons in all of the different versions of a transcript.
For example for TP53 I need to get the exonic coordinates for NM_000546.6, NM_000546.5, .... , all the way through NM_000546.1
I know how to use UCSC or BioMart to get this data for the latest version of the transcript. I've started looking through NCBI's e-utils but not finding options for getting the genomic coordinates for the exons.
