Dear Rod,
Thank you for using the UCSC Genome Browser and your question about the UCSC genes track on hg19 around the region of the gene MYC.
Our engineers have looked at this area and share that it appears this is consequence of the difficulty to build gene models exactly correct in all circumstances in regards to the layers of algorithms involved to collect exons into a final prediction. It does indeed look as though there was an error in the prediction of some transcripts labeling them as MYC when they are more correctly PVT1 transcripts.
On the most recent human assembly, hg38, we have switched our default displayed gene model set to be based upon Ensembl/GENCODE data, which incorporates manual annotations rather than being entirely computationally based.
Ensembl/GENCODE tracks are also available on hg19. You may wish to switch to using the Ensembl/GENCODE prediction models for hg19, here is a session link to these various tracks displayed:
