Biomarkers for bipolar disorder and schizophrenia
View Patent ↗The present invention provides combinations of biomarkers that can be used in the diagnosis and differentiation of bipolar disorder and schizophrenia. The present invention therefore provides methods of differentiating, diagnosing and treating bipolar disorder and schizophrenia, by examining relevant proteins and RNA in a patient sample.
1. A method for determining a gene expression in a blood sample from a subject having, or being suspected of having, schizophrenia or bipolar disorder consisting of performing a gene expression assay on a blood sample from the subject and measuring the mRNA expression level of SH3YL1, SLC44A5, HADHA, CPA3, OXTR, CCDC109B, TREML4, TRIM4, PTGDS, HPR, EEF2, ZMYND8, TBC1D1, TCEAS, ILSRA, GYLTL1B, FADS2, CRIP2, DDX5, and HLA-DRB5.
2. The method of claim 1 , wherein the mRNA expression level is measured by hybridization of a gene array consisting of probes for said genes, RT-PCR, northern blot, nuclease protection, real time PCR, branched DNA, nucleic acid sequence based amplification (NASBA), RNA sequencing, digital droplet PCR, or differential display.
3. The method of claim 1 , wherein the subject is a human male less than 30 years old.
4. The method of claim 1 , wherein the subject is at high clinical risk, in a prodromal phase, and not yet diagnosed with schizophrenia.
5. The method of claim 1 , wherein the subject is at high clinical risk, in a prodromal phase, and not yet diagnosed with bipolar disorder.
