Ensembl and NCBI have been working to align the GENCODE and RefSeq reference transcripts. As part of that effort, we are also developing plans to define a primary transcript for every gene as well as a minimal set of clinically relevant transcripts. To guide that effort, we have developed a small survey to get input on how to define the primary transcript and whether this would be important to your work.
The survey should only take 10 minutes or less and you will have the opportunity to sign up for follow-up info about this project if you are interested.
