[ensembl-dev] Do pseudogenes' have a "parent gene" annotation?

Hi Luke and Vang,
No we don't store this information. One way to do it would be to get the supporting evidence for your pseudogene, I would expect one protein evidence. Then search for protein coding transcripts which also have this protein as supporting evidence. I don't know how reliable it would be.

Regards
Thibaut

I think if I have time or someone at ENSEML can do faster, it is possible to check the pseudogene prediction/annoation process and extract information from there.

I've already written a script that works for pseudogenes like PMS2, where the pseudogene's official symbol is the parent's gene symbol + some other characters, excluding splits in the middle of multi-digit numbers. However, this does not capture all parent genes, and will have some false positives, too.
