The present invention provides methods and kits for the diagnosis of schizophrenia, which employ mitochondrial complex I as a peripheral biological marker for schizophrenia. In an embodiment of the invention, the present invention provides a method for diagnosing schizophrenia in a subject by determining the level of m-RNA or protein mitochondrial complex I subunits and its activity by determining the cellular basal respiration through complex I enzyme.

Methods and kits for diagnosis of schizophrenia

The present invention provides methods and kits for the diagnosis of schizophrenia, which employ mitochondrial complex I as a peripheral biological marker for schizophrenia. In one embodiment, the present invention provides a method for diagnosing schizophrenia in a subject by determining the level of activity of a mitochondrial complex I enzyme in a sample obtained from the subject, and comparing the level of activity in the sample with a normative value of mitochondrial complex I enzyme activity, wherein an altered level of activity of mitochondrial complex I enzyme in the sample compared with the normative value is indicative of the subject having schizophrenia. In another embodiment, the present invention provides a method for diagnosing schizophrenia in a subject by determining the level of m-RNA or protein of mitochondrial complex I in a sample obtained from the subject, and comparing the level m-RNA or protein of mitochondrial complex I in the sample with a normative value of mitochondrial complex I m-RNA or protein, wherein an altered level of mitochondrial complex I m-RNA or protein in the sample compared with the normative value is indicative of the subject having schizophrenia. Kits for diagnosing schizophrenia using the methods of the present invention are also disclosed.
