Genes affected

IRF2BP2 (HGNC:21729): (interferon regulatory factor 2 binding protein 2) This gene encodes an interferon regulatory factor-2 (IRF2) binding protein that interacts with the C-terminal transcriptional repression domain of IRF2. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]
