A Bayesian Analysis for Identifying DNA Copy Number Variations Using a Compound Poisson Process
To study chromosomal aberrations that may lead to cancer formation or genetic diseases, the array-based Comparative Genomic Hybridization (aCGH) technique is often used for detecting DNA copy number variants (CNVs). Various methods have been developed for gaining CNVs information based on aCGH data. However, most of these methods make use of the log-intensity ratios in aCGH data without taking ...
متن کاملBayesian Disease Classification Using Copy Number Data
DNA copy number variations (CNVs) have been shown to be associated with cancer development and progression. The detection of these CNVs has the potential to impact the basic knowledge and treatment of many types of cancers, and can play a role in the discovery and development of molecular-based personalized cancer therapies. One of the most common types of high-resolution chromosomal microarray...
متن کاملAssessment of mitochondrial DNA copy number in peripheral blood leukocyte of opiate abusers and healthy individuals
Background: Based on the studies, variation in the mitochondrial DNA (mtDNA) copy number in peripheral blood leukocytes is associated with increased susceptibility to diseases including cancer. Opiate abusers are at high risk for diseases. In this study, we measured the mtDNA copy number in peripheral blood leukocytes in a group of opiate abusers compared with those in healthy individuals. Met...
متن کاملHigh-resolution analysis of DNA copy number using oligonucleotide microarrays.
Genomic copy number alterations are a feature of many human diseases including cancer. We have evaluated the effectiveness of an oligonucleotide array, originally designed to detect single-nucleotide polymorphisms, to assess DNA copy number. We first showed that fluorescent signal from the oligonucleotide array varies in proportion to both decreases and increases in copy number. Subsequently we...
متن کاملSimplified low-copy-number DNA analysis by post-PCR purification.
Frequently, evidentiary items contain an insufficient quantity of DNA to obtain complete or even partial DNA profiles using standard forensic gentotyping techniques. Such low-copy-number (LCN) samples are usually subjected to increased amplification cylces to obtain genetic data. In this study, a 28-cycle polymerase chain reaction (PCR) was used to evaluate various methods of post-PCR purificat...
