Dear Dr Huber,
Thanks for the reply.
You are right that CDC2L1 is the previous name for CDK11B, and CDC2L2
for CDK11A. I guess I was confused by the output given by BioMart, in
which the match between old names and new names totally are random
(see the previous post). Could be errors in BioMart (table-join)?
