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]
MN1 Gene-Disease associations (from GenCC):
  • CEBALID syndrome
    Inheritance: AD Classification: STRONG Submitted by: G2P, Ambry Genetics, Labcorp Genetics (formerly Invitae)
  • familial meningioma
