    Abstract:

    AIM: To investigate neurofibromatosis type 2 (NF2) gene mutation at mRNA levels in sporadic orbitocranial meningioma and its association with progesterone receptor (PR) mRNA expression. METHODS: This was a case-control study. Thirty-four sporadic meningioma patients with no familial NF2-related meningioma history were recruited. They were interviewed for their obstetric, gynecologic, and contraception history. PR investigation was performed with real-time polymerase chain reaction (PCR). NF2 mutation was investigated using Qbiomarker Somatic Mutation PCR Assay at NF2 mRNA level after its cDNA extraction (four mRNA mutation cytoband coordinates for nucleotide change: c.634C>T/p.Q212, c.655G>A/p.V219M, c.784C>T/p.R262 and c.1228C>T/p. Q410). RESULTS: After mutation analysis at mRNA level, NF2 gene mutation was found in 35.29% patients. Non-mutation group was strongly associated with exogenous hormonal exposure (non-mutation vs mutation: 95.5% vs 83.3%, P<0.001). PR mRNA was found significantly lower in non-mutation group (P=0.033) which presumed as long term exogenous progesterone exposure. However, mutation group was associated with higher rate of progression to grade II (mutation vs non-mutation, 18.2% vs 5%, P<0.001) and was associated more in fibrous and anaplastic tumor tissue. CONCLUSION: NF2 mutation-meningioma is associated with higher grade of meningioma. Non NF2 mutation-meningioma is strongly associated with exogenous progesterone exposure and lower PR expression.
