Abstract: The present invention pertains to methods for classifying tumorous diseases based on their specific genomic DNA methylation profile. The invention provides a method that allows for a classification of a tumor sample obtained from a patient by analysing a multitude, preferably genome wide, collection of CpG positions by comparison to a classification rule derived from a set of methylation data acquired from pre-classified tumor species. The invention is in particular useful for classifying brain tumor samples since brain tumors are characterized by a large variety of distinct tumor species which have different prognostic values and require in the clinic a for each species developed treatment regime.

Abstract: The present invention relates to a method for detecting (D)-2-hydroxyglutarate or (D)-2-hydroxyadipic acid in a sample, the method comprising the steps of: a) contacting a sample with a reagent mixture, wherein said reagent mixture comprises: (i) a solvent, (ii) a dye having an oxidized state and a reduced state, wherein the reduced state can be distinguished from the oxidized state and wherein the dye is initially present in the oxidized state, (iii) an electron transfer agent, (iv) a (D)-2-hydroxyglutarate dehydrogenase enzyme, and (v) a cofactor; and b) detecting (D)-2-hydroxyglutarate or (D)-2-hydroxyadipic acid by measuring the production of the reduced state of the dye. The invention further pertains to a method for diagnosing and/or monitoring a (D)-2-hydroxy-glutarate-associated disease in a subject. Encompassed by the invention is also a method for diagnosing a mutation in an isocitrate dehydrogenase (IDH) gene or in a (D)-2-hydroxyglutarate (D2HG) dehydrogenase enzyme gene in a subject.

Abstract: The present invention relates to the field of diagnostic tests and diagnostic tools. Specifically, contemplated is to a method for diagnosing cancer in a sample of a subject suspected to suffer from cancer comprising contacting the sample with an antibody which specifically binds to the epitope characterized by SEQ ID NO 1 on a BRAF polypeptide under conditions which allow for binding of said antibody to the epitope and determining binding of the antibody to the epitope, whereby cancer is diagnosed. Further contemplated are antibodies which specifically bind to the epitope characterized by SEQ ID NO 1 on a BRAF polypeptide and a device or kit comprising such antibodies.
