Epigenomic Alterations

MGMT promoter methylation (73%)[27] [28]

Genes and Main Pathways Involved

Put your text here and fill in the table (Instructions: Please include references throughout the table. Do not delete the table.)

Gene; Genetic Alteration Pathway Pathophysiologic Outcome
Homozygous deletion of CDKN2A, CDKN2B, RB1, and CDK4 RB pathway Increased cell growth and proliferation Negatively correlated with overall survival[29]
Amp of PDGFRA and activating mutations in PI3K genes RTK-PI3K-mTOR Increased activation induces cell cycle progression[30]  

Genetic Diagnostic Testing Methods

·      Initial diagnostic workup is performed by using routine immunohistochemical panel which involves IDH1 R132H, p53 and ATRX IHC

·      In case of negative and indeterminate IHC results, sequencing need to be performed for IDH1 codon 132 and IDH2 codon 172, to detect non-canonical (non-R132H) IDH1/2 mutations.

Familial Forms

·      Generally sporadic but low frequency SNP at 8q24.21 associated with increased risk[31]

·      Variants at 8q24.21 (CCDC locus), PHLDB1, AKT3, IDH1, D2HGDH[32]

·      Li-Fraumeni syndrome characterized by germline TP53 mutations[33]

·      IDH1R132C mutations in tumors with germline TP53 mutation[34]

·      Patients with inherited Ollier disease[35]

·      Germline mutations in mismatch repair genes (pediatric and adults)[36]
