  • Patent number: 10309967
    Abstract: Methods of diagnosing, confirming a diagnosis of, and determining a predisposition for a bipolar disorder in a subject are provided. An amount of at least one of biomarker from the cerebrospinal fluid and/or serum of a subject is measured, for example, isocitric acid. The amount of the at least one biomarker can be compared with a control amount of the at least one biomarker in a corresponding sample collected from a subject without the bipolar disorder. An increase or decrease in the amount of the particular biomarker or biomarkers measured can be indicative that the subject has the bipolar disorder or a predisposition for the bipolar disorder. Methods of identifying a compound for preventing and/or treating a bipolar disorder are also provided based on the expression level of an isocitric acid dehydrogenase 3 alpha and/or beta-subunit gene, and/or based on one or more metabolite biomarker.

  • Publication number: 20150309053
    Abstract: A novel test method for testing for the presence or absence of a predisposition to autistic spectrum disorder or the presence or absence of development of autistic spectrum disorder is provided. The test method includes a test step of determining an amount of at least one of the fatty acid binding proteins FABP3, FABP4, FABP5, and FABP7 in a sample prepared from the living body of a human or determining an expression level of at least one of the FABP3, FABP4, FABP5, and FABP7 genes in the sample.

  • Publication number: 20050019822
    Abstract: The present invention relates to a method for diagnosing panic disorder, said method being based on the determination of the class of polymorphism of the short tandem repeat (STR) complex in the upstream region of human cholecystokinin gene. The polymorphic DNA comprises a DNA sequence, having a general formula (1): 5?(GGAA)n1X(GGAG)n2(GGAA)n3(GGGA)n4GAG(AGAC)n5Y(GGAA)n63???(1) wherein X denotes a DNA sequence of SEQ ID NO:1, Y denotes a DNA sequence of SEQ ID NO:2 and each of n1, n2, n3, n4, n5 and n6 denotes independently 0 or a positive integral number, whereby said DNA ranging from 363 to 399 base pairs in length. The invention also relates to an assay kit used for implementing said method.

  • Publication number: 20030170668
    Abstract: Methods and compositions are provided for determining a genotype associated with increased susceptibility to manic-depressive illness. The genotype is determined using markers for a region of chromosome 18 exhibiting linkage disequilibrium with manic-depressive illness. The invention also provides for a novel myo-inositol monophosphatase protein encoded for on chromosome 18.
