Abstract: A system and method for region-based calling utilizes a probability distribution of a phi-transformed logarithmic ratio to determine a set of possible transition paths through markers and marker states, constructs a local evidence matrix for each of the markers and generates a total per-marker value for each segment in a discrete region.

Abstract: Methods for diagnosis and surveillance of complex multi-factorial disorders such as cancer by screening of easily accessible biomarkers are disclosed. Highly stable cell free Circulating Nucleic Acids (CNA) present as both RNA and DNA species have been discovered in the blood and plasma of humans. Correlations between tumor-associated genomic/epigenetic/transcriptional changes and alterations in CNA levels are strong predictors of the utility of this biomarker class as clinical indicators. Methods for using microRNAs (miRNAs) representing a class of naturally occurring small non-coding RNAs of 19-25 nt as markers that can associate their specific expression profiles with cancer development are disclosed. Methods for isolating plasma fractions for the study of miRNA biomarkers and for measurement of circulating miRNA levels are disclosed.

Abstract: Methods for diagnosing inflammatory bowel disease and ulcerative colitis using miRNA biomarkers for these diseases are provided. Differential expression of the miRNA biomarkers in blood fractions, e.g., platelets, of diseased individuals as compared to expression levels in normal individuals indicates the presence of IBD or ulcerative colitis. Also provided are microarrays for use in the diagnostic methods, wherein the features of the microarray consist essentially of nucleic acid sequences that hybridize to the miRNA biomarkers and normalization controls.
