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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2022The c.3892G>A (p.V1298M) alteration is located in exon 2 (coding exon 2) of the MN1 gene. This alteration results from a G to A substitution at nucleotide position 3892, causing the valine (V) at amino acid position 1298 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
