Hi UCSC team, I am using the UCSC known gene (hg18) as annotation. And I use kgXref.txt to convert UCSC transcript IDs to refSeq IDs and assign them gene symbols accordingly. However, I found that some genes do not have gene symbols in kgXref.txt. For instance, the transcript 'uc003lob.1' is an isoform of the gene 'TCERG1'--the other isoform of this gene is uc003loc.1, which could be displayed on the genome browser. Neither uc003lob.1 nor uc003loc.1 could be found in kgXref.txt.
I wonder if there is a "latest" version of kgXref.txt, or there is a better file to help convert UCSC IDs to gene symbols. Thank you very much.
