Genes affected

DIP2A (HGNC:17217): (disco interacting protein 2 homolog A) The protein encoded by this gene may be involved in axon patterning in the central nervous system. This gene is not highly expressed. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]
