Is there a source or a way to get current transcript versions from a list of NCBI gene id's or by using the gene symbol? I have tried LRG_RefSeqGene and that seems to work but only for ~3600 of my 4700 genes.

For example, my data is tab delimited and by using awk I can search LRG for a match but all of them are not found. Maybe it is better to use the NCBI ID but I am not sure. Thank you :).

NCBI ID Symbol
 2      A2M
 53947  A4GALT
 51146  A4GNT
 8086   AAAS
 13     AADAC

Can UCSC mysql be used and return the NCBI ID as well as transcript. For example,

mysql --user=genomep --password=password --host=genome-mysql.cse.ucsc.edu -A -D hg19 -e 'select distinct refGene.name,gbCdnaInfo.version from refGene,gbCdnaInfo WHERE refGene.name=gbCdnaInfo.acc' > refseq_version.txt

refseq_version.txt
name    version
NM_000014   4
NM_000015   2
NM_000016   5

Can NCBI ID be added to this list?
