Sometimes a specific version of a transcript is not available in our mapping database for hg19 and is thus rejected by the position converter. In many cases, this version will be available in our mapping database for hg18 with a re-mapping to a newer version of the transcript (which is available on hg19.
Proposal: if the above situation arises and the coordinates on the re-mapped newer transcript version via hg18 are the same as the coordinates on the originally requested transcript version, automatically use this to do the position conversion.
The same also applies to how we create the UCSC Genome Browser link.
