Pathway recognition algorithm using data integration on genomic models (paradigm)

Abstract

A patient sample specific dynamic pathway map is constructed on the basis of measured patient data and a probabilistic pathway model that is based on attributes for pathway elements, wherein some attributes for pathway elements are known a priori, where other attributes for the pathway elements are assumed, and where the pathway elements are cross-correlated and assigned an influence level for at least one pathway. Preferred dynamic pathway maps provide context of the measured patient data with respect to a selected reference pathway activity.

AI Technical Summary

Problems solved by technology

However, while SPIA provided significant advantages in interpreting cancer datasets using pathway topology, SPIA is generally limited to using only a single type of genome-wide data.

Consequently, as information for gene copy number, DNA methylation, somatic mutations, mRNA expression, and microRNA expression are not integrated into SPIA, analytic and predictive value of SPIA remains highly restricted, particularly where a more global analysis is required.

Still further, all or almost all of the currently known pathway analyses fail to incorporate interdependencies among genes in a pathway that can increase the detection signal for pathway relevance.

Therefore, even tough numerous systems and methods of pathway analysis known in the art, all or all of them suffer from one or more disadvantage.
