Abstract: Disclosed are methods and systems for detecting methylation of the promoter of O-6-methylguanine-DNA methyltransferase gene (MGMT). In particular, the methods and systems may be utilized to detect methylation in the MGMT promoter in a DNA sample from a glioblastoma and optionally in order to predict whether a subject having the glioblastoma will respond to treatment with an alkylating agent. The methods and systems typically include a step of deep-sequencing the DNA sample after the DNA sample has been treated with a reagent that converts unmethylated cytosine to uracil such as a bisulfite reagent.

Abstract: Disclosed are methods for assessing the methylation and mutation status of nucleic acid in a sample. The methods provide for methylation-dependent modification of the nucleic acid in a sample, and subsequently nucleic acid amplification processes to distinguish between mutated and non-mutated target sequence.
