# Distinguishing Splicings that Produce Functional Transcripts Amongst Alternates Shown

This is a link to the UCSC Genome Browser showing a portion of Ch 17 containing TP53 here.

There are several representations of the gene of varying length and number of exons. I presume these are equivalent to alternate splicings.

Assuming this presumption is correct(?), how can I determine which result in RNAs that are experimentally verified?

Now. to get the sequence of a transcript or covert a variant Ensembl drops the ball. There is no clear web tab that I know of. Nor an API route. ftp://ftp.ensembl.org/pub/release-99/fasta/homo_sapiens/pep/Homo_sapiens.GRCh38.pep.all.fa.gz contains all the sequences however. For a project of mine (ENSTMapper in this link) to map an amino acid mutation on one transcript to another I ended up write my own short converter, although there are a few similar tools out there.
