Hi Bibek, We only display RefSeq genes that make it through our alignment process. More information about our alignment process can be found on the RefSeq description page here: http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg18&g=refGene.
I hope this information is helpful. Please feel free to contact the mail list again if you require further assistance.
