Genes affected

MN1 (HGNC:7180): (MN1 proto-oncogene, transcriptional regulator) Meningioma 1 (MN1) contains two sets of CAG repeats. It is disrupted by a balanced translocation (4;22) in a meningioma, and its inactivation may contribute to meningioma 32 pathogenesis. [provided by RefSeq, Jul 2008]
