BIRC5 Genomic Copy Number Variation in Early-Onset Breast Cancer
Background: Baculoviral inhibitor of apoptosis repeat-containing 5 (BIRC5) gene is an inhibitor of apoptosis that expresses in human embryonic tissues but it is absent in most healthy adult tissues. The copy number of BIRC5 has been indicated to be highly increased in tumor tissues; however, its association with the age of onset in breast cancer is not well understood. Methods: Forty tumor tiss...
متن کاملCopy Number Variation in Familial Parkinson Disease
Copy number variants (CNVs) are known to cause Mendelian forms of Parkinson disease (PD), most notably in SNCA and PARK2. PARK2 has a recessive mode of inheritance; however, recent evidence demonstrates that a single CNV in PARK2 (but not a single missense mutation) may increase risk for PD. We recently performed a genome-wide association study for PD that excluded individuals known to have eit...
متن کاملDetermination of Beta-Defensin Genomic Copy Number in Different Populations: A Comparison of Three Methods
BACKGROUND There have been conflicting reports in the literature on association of gene copy number with disease, including CCL3L1 and HIV susceptibility, and β-defensins and Crohn's disease. Quantification of precise gene copy numbers is important in order to define any association of gene copy number with disease. At present, real-time quantitative PCR (QPCR) is the most commonly used method ...
متن کاملCopy number variation accuracy in genome-wide association studies.
BACKGROUND/AIM Copy number variations (CNVs) are a major source of alterations among individuals and are a potential risk factor in many diseases. Numerous diseases have been linked to deletions and duplications of these chromosomal segments. Data from genome-wide association studies and other microarrays may be used to identify CNVs by several different computer programs, but the reliability o...
متن کاملCurrent analysis platforms and methods for detecting copy number variation.
Copy number variation (CNV), generated through duplication or deletion events that affect one or more loci, is widespread in the human genomes and is often associated with functional consequences that may include changes in gene expression levels or fusion of genes. Genome-wide association studies indicate that some disease phenotypes and physiological pathways might be impacted by CNV in a sma...
