Genes affected
THOC2 (HGNC:19073): (THO complex subunit 2) The TREX multiprotein complex binds specifically to spliced mRNAs to facilitate mRNA export. The protein encoded by this gene is a member of the THO complex, a subset of the TREX complex. The encoded protein interacts with the THOC1 protein.[provided by RefSeq, Jun 2010]
