METHODS AND COMPOSITIONS FOR DISEASE PROGNOSIS BASED ON NUCLEIC ACID METHYLATION

摘要

A large scale DNA methylation study was perfomred in patients with acute myeloid leukemia (AML) that revealed quantitative methylation patterns correlated with patient survival. Based on these results, a prognostic model was built which categorizes a patient's risk - either in a good or poor prognosis group. The findings provided herein support the use of genomic methylation markers for improved molecular classification and disease management in adult AML. Also, the results provide insight into the pathophysiology of AML and offer novel AML gene targets. Thus provided are methods and compositions for the prognosis of a subject suffering from acute myeloid leukemia (AML) based on the methylation state of nucleic acids. The methods may used alone to determine a patient's prognosis or in combination with other prognostic factors or markers such as gene expression.
