I initially thought about this, but since a “transcript” would typically refer to a rearranged locus, it would require additional annotation (mainly the CDR3), which I consider to be beyond the scope of segment nomenclature. This does of course not mean that we should not have a standardized way on how to annotate such transcripts, but I guess that this is already worked upon by the people of the repository group (like here or here). Or where you thinking about “sterile” (i.e. non-rearranged) transcripts?
