Hi Aly,

Gene and gene prediction data can be generated through computer 
processes or through manual curation by researchers - it is a good idea 
to look at the track descriptions to see how a particular gene set was 
created. UCSC Genes is based in part on RefSeq 
(http://genome.ucsc.edu/cgi-bin/hgGene?hgg_do_kgMethod=1), so it is not 
surprising UCSC Genes shows ANKRD30B to chr18, same as RefSeq. We also 
show a related pseudogene on chr21. Information about how Ensembl builds 
their gene set can be found here: 
http://www.ensembl.org/info/docs/genebuild/genome_annotation.html.

I hope this information is helpful.  Please feel free to contact the 
mail list again if you require further assistance.

Best,
Mary
