About DNAPrint genomics

DNAPrint genomics, Inc. will provide practitioners of genomic research and personalized medicine with a comprehensive system for disease dissection and patient classification. Physicians will be able to use the company's system, through a combination of on-site hardware/software placement and ASP (application-service provider) resources, to draw highly sophisticated conclusions and associations between patient genotype data and database patterns from historical studies. Many of these studies will be performed by DNAPrint genomics and/or it's partners. The analytical heart of the system is a collection of sophisticated algorithms that enable a progression from the multivariate dissection of high-density genotype matrices to multi-dimensional associations with complex human traits. The system uses a variety of novel mathematical modeling and programming techniques, which comprise the bulk of the companies budding intellectual property portfolio. The company has already filed patent applications for a genetic analysis reagent that confers considerable advantages for high-throughput DNA sequencing and genotyping, and has filed applications for five trade and/or service marks connected with the companies business model. The company intends to patent the application of its informatics platform to the field of genomic research and for personalized medical applications.

During the development phase of this informatics platform, the company performs genetic variation studies on a number of different target areas, including drug response and cancer. Not only do these targets provide a comprehensive training set for the algorithms and models developed by the company, but the genetic patterns discovered through the analysis represent separate, and valuable assets. For example, the application of the informatics platform to patients which exhibit side-effects for a certain drug can produce a valuable diagnostic product which could reduce patient morbidity associated with the use of that drug. The company intends to patent and use these "information" assets to generate near-term revenue growth and profitability. DNAPrint genomics Inc. was founded by a group of scientists with research and commercial experience in high-level mathematical modeling, programming and molecular genetics.
