Hi, I am interested to download RefSeq track file of Human hg18 from UCSC genome browser. For this, I selected assembly hg18, group: Gene and Gene Prediction Tracks, track: RefSeq Genes and table: refGene. This downloaded file corresponds to total of 36517 entries, that in turn corresponds to 34806 genes with unique accession numbers. Even i downloaded refGene file of hg18 from ftp site as well.
I also downloaded RefSeq RNA sequences (rna.gbk), NCBI build 36.1 from RefSeq ftp site. This NCBI refseq file has 41,726 genes with unique accession numbers. My question is, although i am using same genome version hg18 (as NCBI Build 36.1 is equivalent to hg18) from both of these sources, why there is difference in number of genes listed. Why number of genes listed in UCSC RefSeq track file is only 34,806, which is less than what is listed in NCBI RefSeq. How can i get a refseq track file (hg18) which should enlist all 41,726 genes found in NCBI Build 36.1 RefSeq. Waiting for an early response. thanks & regards, Bibek IMPORTANT NOTICE: This e-mail and any attachments may contain confidential or sensitive information which is, or may be, legally privileged or otherwise protected by law from further disclosure.
