Bed file of union of all transcripts for a set of genes

Question

[Floydian_slip]

Hi, I have a set of 100 genes and I want to obtain a bed file containing a union of all transcripts for each of those genes with hg19. IOW, for each gene, I want a bed file that contains the union of all reported transcripts for that gene. What is the fastest/best way to do so? Thanks!

Example input: a list of genes such as BRCA1 and ALDH1. Desired output: a bed file containing their transcripts. I understand there will be multiple lines for each for each of the transcript regions. Thanks!

I was referring to pasting some real data examples, like a table that shows how things should look, not just words. You already explained with words in your question, but no coded solution yet because people do not know how exactly the data look like.

I'd grep a gtf with the gene list and use bedtools merge on the result.
