Abstract: The present invention provides a method of identifying one or more epigenetic markers associated with psychosis-associated diseases such as bipolar disease or schizophrenia, the method comprising a) obtaining a first group of samples comprising genomic DNA from a plurality of bipolar or schizophrenic subjects and a second group of samples comprising genomic DNA from a plurality of control subjects; b) performing DNA methylation analysis to determine methylation differences in one or more DNA regions between the first group and second group of samples, wherein a methylation difference in a DNA region is indicative of an epigenetic marker associated with bipolar disease or schizophrenia. The invention also provides one or more epigenetic markers associated with psychosis-associated diseases such as bipolar disease or schizophrenia.

Abstract: The invention can be summarized as follows. There is provided a method for analyzing DNA methylation profiles of cell-free DNA in body fluids by enriching a methylated or unmethylated fraction of DNA from cell-free DNA and subjecting the enriched DNA to microarray based methylome profiling and bioinformatics data analysis.

Abstract: The invention can be summarized as follows. There is provided a method for amplifying hypomethylated genomic nucleotide sequences and/or hypermethylated genomic nucleotide sequences and comparing the methylation state between different samples, for example control and test samples. Also disclosed is a microarray based method for analyzing hypo and/or hypermethylated genomic nucleotide sequence. Further, kits comprising reagents for practicing the method are provided.

Abstract: The present invention provides a method of detecting an epigenetic abnormality associated with a disease. The method comprises identifying, within a eukaryotic genome, a locus having a hypomethylated sequence specific for the disease and an endogenous multi-copy DNA element. The method can also comprise separate steps of identifying a disease-specific hypomethylated sequence and identifying an endogenous multi-copy DNA element, where the steps may be performed in any order, so long as a locus is identified that has both a disease-specific hypomethylated sequence and an endogenous multi-copy DNA element. The disease-specific hypomethylated sequences detected in accordance with the present invention indicate putative regions of epigenetic dys-regulation and indicate aberrantly regulated nucleic acid sequences that may cause or predispose a patient to disease, such as, but not limited to, Huntingdon s disease, cancers, diabetes, schizophrenia, or bipolar disorder.
