[Genome] absent mRNA accession

[Archana Thakkapallayil]

Hello Ines Mollet,

As of April, 2007, sequences from genbank are no longer included if they 
contain the following as part of the record:

http://fulllength.invitrogen.com

Some of these entries are the result of alignment to pseudogenes, 
followed by "correction" of the mRNA to match the genomic sequence. It 
is therefore not the sequence of the actual mRNA and makes it appear 
that the mRNA is transcribed. Invitrogen no longer sells the clones.

This is mentioned in our mRNA description page here:
http://www.genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg18&c=chrX&g=mrna

All of the mRNAs that you have listed contains the above information in 
the record. I hope that this is helpful to you.  Please don't hesitate 
to contact us again if you require further assistance.

Regards,

Archana
