In high-dimensional genome-wide (GWA) data, a key challenge is to detect genomic variants that interact in a nonlinear fashion in their association with disease. Identifying such genomic interactions is important for elucidating the inheritance of complex phenotypes and diseases. In this paper, we introduce a new computational method called Informative Bayesian Model Selection (IBMS) that lever...

A variety of data analysis concerned with genome sequences support the proposal that each living organism owns a genomic signature. Classical approaches to the genomic signature deciphering are based on the counting of oligonucleotides in DNA sequences. Statistical tools as well as graphical representations have been used to associate genomic signatures with oligonucleotides frequencies in the ...

The increasing recognition that symbioses have greatly altered evolution through genome fusions is creating a need for algorithms that can reliably detect and reconstruct fusions. Here, we generalize the bootstrappers gambit algorithm (a quartet method) in order to permit it to analyze both bifurcations and fusions under a single mathematical model, and thereby detect past genomic branchings an...

Background: DNA polymerase β (pol β) is a key enzyme of base excision repair pathway. It is a 1-kb gene consisting of 14 exons. Its catalytic part lies between exon 8 and exon 14. Exon 12 has a role in deoxyribonucleotide triphosphate selection for nucleotide transferase activity. Methods: Genomic DNA was isolated from ovarian carcinoma samples. Single strand conformation polymorphism...

UNLABELLED Dblox and RDblox provide a simple statistical test for duplicated genomic structure; the same programs can also be used to identify putatively duplicated regions. The method focuses on ancient duplication events involving protein-coding genes. AVAILABILITY http://www.biol.sc.edu/~austin/
